feat: Add golang autodiscovery policy support for Gitea/Gitlab/Stash/Bitbucket

[olblak]

This pullrequest is not designed to be merged but as a proof of concept to use the partial feature suggested from
updatecli/updatecli#5508

Description

Test

To test this pull request, you need a custom Updatecli build
based on updatecli/updatecli#5508

Then you can run the following commands:

updatecli manifest show --config updatecli/policies/golang/autodiscovery/updatecli.d/ --values updatecli/policies/golang/autodiscovery/values.yaml --values updatecli/policies/golang/autodiscovery/testdata/values.yaml --debug

One nit: It'd be nice to have a scm.token_env value for gitea, as there's no standard way to pass a token in. Gitea/forgejo actions both expose a GITHUB_TOKEN env var with a gitea/forgejo token, but it's not valid for writing, or opening PRs, or anything. It's just valid for pulling the repo, so to get write access for opening PRs or similar at the moment, it's required to set a secret and pass it in as an env variable.

@AmandaCameron Could you have another look? It should be good.
If it's fine to you, I can start adding support for other policies as well, if you have a list of policies that you need, I can start with them but it's gonna take me some time

Pull Request Overview

Adds proof-of-concept support for auto-discovery policies against multiple SCM platforms in Go (Gitea, GitLab, Stash, Bitbucket).

• Extend values.yaml with scm.kind, env_token, and optional commitusingapi settings.
• Simplify default template, pin version v0.103.0, and split SCM-specific logic into separate _scm.*.yaml files.
• Bump policy version to 0.10.0 and update the changelog.

Comments suppressed due to low confidence (2)

updatecli/policies/golang/autodiscovery/values.yaml:10

• Update the comment to list all supported SCM kinds (github, gitea, gitlab, stash, bitbucket) to keep documentation in sync with the new templates.

  # Accepted values: github, gitea

updatecli/policies/golang/autodiscovery/updatecli.d/_scm.bitbucket.yaml:2

• The variable name $GitbucketPAT is inconsistent with other SCM templates ($BitbucketPAT). Renaming it to match the pattern would improve consistency.

# {{ $GitbucketPAT := env .scm.env_token }}

Sorry for delay getting back, currently on vacation so I've spent a lot of time away from my laptop.

Looks good, the other policies I'd probably be using short-term is forgejo/github actions autodiscovery, as well as updatecli policy updates.
