Provision two new Gitea repos for the LiteLLM dynamic secrets work: the
Vault/OpenBao secrets-engine plugin and its companion Terraform provider.
- Add config/.../repository/vault-plugin-secrets-litellm.yaml
- Add config/.../repository/terraform-provider-litellm.yaml
- Default branch main, squash-only merging (allow_* flags, since the
go-gitea/gitea provider has no default_merge_style), and branch protection
on main requiring pre-commit/build/test checks with Owners approval
