GitHub support for infra repo

[shekharc-in]

Add provider, url, and org fields to Repository CRD

Summary

Adds three optional fields to RepositorySpec so the Nephio infrastructure
controllers can target git providers other than Gitea.

This is the API half of GitHub provider support; the controller implementation
is a companion PR against nephio-project/nephio.

Changes

Field	Type	Description
provider	*string	Git provider type. Enum: gitea, github, gitlab. Defaults to gitea.
url	*string	Base URL for the git provider API. Required for Gitea, optional for GitHub/GitLab.
org	*string	Organization / owner name for the repository.

All three are +optional. provider carries
+kubebuilder:validation:Enum=gitea;github;gitlab and
+kubebuilder:default=gitea.

Regenerated config/crd/bases/infra.nephio.org_repositories.yaml and
infra/v1alpha1/zz_generated.deepcopy.go accordingly.

Why

Repository reconciliation is currently Gitea-only, with the endpoint and
owner derived from Gitea-specific configuration. Carrying the provider on the
resource lets a single cluster manage repositories across providers and lets
the controller pick the right client per resource, rather than being fixed at
deployment time.

Hi @shekharc-in. Thanks for your PR.

I'm waiting for a nephio-project member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
