An update that solves one vulnerability can now be installed.

## Description:

This update for shim fixes the following issues:

  * CVE-2022-28737 was missing as reference previously.

  * Upgrade shim-install for bsc#1210382

After closing Leap-gap project since Leap 15.3, openSUSE Leap direct uses shim
from SLE. So the ca_string is 'SUSE Linux Enterprise Secure Boot CA1', not
'openSUSE Secure Boot CA1'. It causes that the update_boot=no, so all files in
/boot/efi/EFI/boot are not updated.

Logic was added that is using ID field in os-release for checking Leap distro
and set ca_string to 'SUSE Linux Enterprise Secure Boot CA1'. Then
/boot/efi/EFI/boot/* can also be updated.
