IPU 9 -> 10: obsolete GPG key with SHA1 signature

[pirat89]

When upgrading to RHEL 10, we have analogical problem as we had for IPU 8 -> 9 due to GPG keys with SHA1 signatures. The SHA1 algorithm is considered unsecure since RHEL 9 and all RPMs are required to be signed by keys with SHA2 signatures. The RHEL 9 GPG (auxiliary) key is unfortunately still signed with SHA1 and RHEL 10 tooling refuse to use it for any operations.

To resolve this apply the same solution as we did in the past:

• obsolete original key
• install the target RHEL 10 GPG keys during the upgrade

jira: RHEL-71517

TODO

• add RHEL 10 GPG key to the trusted dir
  • checked, that present keys are already really the correct ones
• test this manually to see whether it's complete or not :)

Thank you for contributing to the Leapp project!

Please note that every PR needs to comply with the Leapp Guidelines and must pass all tests in order to be mergeable.
If you want to request a review or rebuild a package in copr, you can use following commands as a comment:

• review please @oamg/developers to notify leapp developers of the review request
• /packit copr-build to submit a public copr build using packit

Packit will automatically schedule regression tests for this PR's build and latest upstream leapp build.
However, here are additional useful commands for packit:

• /packit test to re-run manually the default tests
• /packit retest-failed to re-run failed tests manually
• /packit test oamg/leapp#42 to run tests with leapp builds for the leapp PR#42 (default is latest upstream - main - build)

Note that first time contributors cannot run tests automatically - they need to be started by a reviewer.

It is possible to schedule specific on-demand tests as well. Currently 2 test sets are supported, beaker-minimal and kernel-rt, both can be used to be run on all upgrade paths or just a couple of specific ones.
To launch on-demand tests with packit:

• /packit test --labels kernel-rt to schedule kernel-rt tests set for all upgrade paths
• /packit test --labels beaker-minimal-8.10to9.4,kernel-rt-8.10to9.4 to schedule kernel-rt and beaker-minimal test sets for 8.10->9.4 upgrade path

See other labels for particular jobs defined in the .packit.yaml file.

Please open ticket in case you experience technical problem with the CI. (RH internal only)

Note: In case there are problems with tests not being triggered automatically on new PR/commit or pending for a long time, please contact leapp-infra.
