## Description:

This update for spack fixes the following issues:

spack was updated from version 0.21.3 to 0.23.0:

  * Improved documentation generation (bsc#1235144)
  * Version v0.23.0:
  * New features:
    * Spec splicing
    * Broader variant propagation
    * Ability to query specs by namespace
    * `spack spec` now respects environment settings and `unify:true`
    * Improved and polished `spack spec` and `spack find -c` output
    * The command `spack -C <env>` allows to use an environment's configuration without activation
  * New commands, options, and directives:
    * The new `spack env track` command takes a non-managed Spack environment and adds a symlink to Spack's `$environments_root` directory.
    * Added `-t` short option for `spack --backtrace` to output backtrace errors
    * `gc` now allows to garbage-collect specific packages through the command line
    * `oci buildcaches` now supports the option `--only=package`
  * Highlighted bugfixes:
    * Externals no longer override the preferred provider
    * Composable `cflags`
    * Fixed concretizer Unification for included environments
  * Deprecations, removals, and syntax changes:

    * The old concretizer has been removed from Spack, along with the `config:concretizer` config option
    * Best-effort expansion of spec matrices has been removed
    * The old Cray `platform` (based on Cray PE modules) has been removed, and `platform=cray` is no longer supported
    * The `config:install_missing_compilers` config option has beendeprecated
    * Config options that deprecated in `v0.21` have been removed
    * Spack's old test interface has been removed
    * The `spack versions --safe-only` option, deprecated since `v0.21.0`, has been removed
    * The `--dependencies` and `--optimize` arguments to `spack ci` have been deprecated
  * Version 0.22.2:

  * Bugs fixed:

    * Bumped vendored `archspec` for better aarch64 support
    * Fixed regression in `{variants.X}` and `{variants.X.value}` format strings
    * Ensure shell escaping of environment variable values in load and activate commands
    * Fixed an issue where `spec[pkg]` considers specs outside the current DAG
    * Do not halt concretization on unknown variants in externals
    * Improved validation of `develop` config section/
    * Explicitly disable `ccache` if turned off in config, to avoid cache pollution
    * Improved backwards compatibility in `include_concrete`
    * Fixed issue where package tags were sometimes repeated
    * Make `setup-env.sh` "sourced only" by dropping execution bits
    * Make certain source/binary fetch errors recoverable instead of a hard error
    * Do not initialize previous store state in `use_store`
  * Update to 0.22.1.

  * Bugs fixed:
    * Fix reuse of externals on Linux
    * Ensure parent gcc-runtime version >= child
    * Ensure the latest gcc-runtime is rpath'ed when multiple exist among link deps
    * Improve version detection of glibc
    * Improve heuristics for solver
    * Make strong preferences override reuse
    * Reduce verbosity when C compiler is missing
    * Make missing ccache executable an error when required
    * Make every environment view containing `python` a `venv`
    * Fix external detection for compilers with os but no target.
    * Fix version optimization for roots.
    * Handle common implementations of pagination of tags in OCI build caches.
    * Apply fetched patches to develop specs
    * Avoid Windows wrappers for filesystem utilities on non-Windows
    * Fix formatting issue in `spack audit`
  * Other changes:

    * Give 'site' scope a lower precedence than 'system' scope
  * Version 0.22.0:

  * New features:
    * Compiler dependencies are moving from `compilers.yaml` to `packages.yaml`
    * Improved spack find UI for Environments
    * Improved command-line string quoting
    * Revert default spack install behavior to `--reuse`
    * The `install` command now offers three options
