Reverts #10591

This appears to be a one-time workflow run to deprecate the compromised 1.14.1 version of axios. However, both attempted runs appeared to have failed due npmjs already unpublishing the package on their end.

In any event, this is no longer necessary. In the future, once OIDC / Trusted Publishing is adopted (#7055), all tokens should be revoked, and deprecations should be done manually from the npmjs website instead.

Summary by cubic

Reverts the CI deprecate workflow by removing .github/workflows/deprecate.yml. This cleans up a one-off action for axios@1.14.1 and prevents accidental or failing runs.

Description

• Summary of changes: remove .github/workflows/deprecate.yml
• Reasoning: npm already unpublished axios@1.14.1, previous runs failed, and this automation is no longer needed
• Additional context: future deprecations should be done via the npm website; plan to adopt OIDC/Trusted Publishing to avoid long‑lived tokens

Docs

• Remove any references to the deprecate workflow from contributor and release docs
• Add a note: deprecate versions manually via the npm website until OIDC/Trusted Publishing is in place

Testing

• No tests added or changed
• Not needed: CI-only file removal with no runtime impact
