feat: integrated HA-valkey configuration

[JoeHCQ1]

Integrated HA Valkey into our bundle. This required updating the valkey and gitlab packages to the latest versions to get needed upstream changes.

Changes needed by the GitLab update:

• Fixed init security context re: GitLab update where they restricted those by default.
• Overrode a new value to ensure the gitlab object store secret isn't overwritten with Minio default values (the zarf variable wasn't seeming to work)
• Added zarf var so registry bucket wasn't hardcoded value. Technically the bucket has always been wrong in dev and test, but the update meant the registry doesn't become healthy if it can't find it's bucket. Used to not care.

Other:

• Changed Valkey's namespace to gitlab-valkey for future friendliness. GitLab doesn't require that we migrate caches so no downstream impacts.
• Removed gitaly security context because it's just restating the upstream SC.
• Removed the gitaly cgroups PSC declaration because it can only be fixed upstream, se pending PR: https://github.com/defenseunicorns/uds-package-gitlab/pull/246/files

Some of the "other" changes mean that we can get the gitaly init cgroups working again as soon as that PR is merged and a release cut.
