v0 validation callers disabled in favor of CAMARA Validation

[hdamker]

Problem description

Following the merge of #229 which installed the CAMARA Validation workflow (.github/workflows/camara-validation.yml, pinned to camaraproject/tooling@v1-rc), the legacy v0 validation callers have been disabled by the admin team to avoid duplicate validation runs on every PR:

• .github/workflows/pr_validation_caller.yml
• .github/workflows/spectral-oas-caller.yml

The disable was applied via the Actions API; the workflow file(s) remain in the repository so they can be re-enabled as a fallback if needed.

Expected action

No codeowner action required. The disabled workflow files will be removed as part of a dedicated cleanup campaign at v1 GA.
