chore: update gitea chart to 12.x.y

[a1994sc]

Description

Updates gitea chart to 12.0.0:

• The upstream chart replaces redis with valkey, so I disabled the valkey cluster.
• Changed url to use OCI chart
• Changed gitea_image to use ghcr.io endpoint to avoid rate-limiting
  • Might want to consider changing registry_image_* to use ghcr.io endpoints

Hey @a1994sc , would you mind rebasing this when you have a moment? I'd like to see where this lands for review currently.

[a1994sc]

Oh rebase, not merge, yea I can update that later today

[brandtkeller]

E2E without cluster workflows are failing with a hardcoded gitea image

I'd be fine with updating this line again unless you see a more dynamic option available.

[a1994sc]

ok, I think I saw that recent too, so I can update that.

[brandtkeller]

reviewing the delta of updates between the indicated application version as well as the helm chart versions. No action required by the PR.

Appreciative of catching the update on this.

[a1994sc]

Not that is a very exhaustive change, but I have been rolling the latest version of the helm chart/docker image internally without too much issue. However I understand my needs aren't going to fit for the whole zarf user base

[brandtkeller]

Coming back to this (finally) - appreciate the patience. Gitea as an init package component should likely get more attention than we give it to-date.

@a1994sc would you mind updating this PR with a merge commit or rebase (however you prefer). I'd love to get this over the line soon.

Recognizing gitea has released more updates since. I am good with keeping this update as-is or updating the artifacts to the latest releases.

[a1994sc]

@brandtkeller I think it would be "better" to update the artifacts to the latest, so I will update that in the next little bit.
