chore: update gitea chart to 12.1.2

[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.

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.

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
