Wire Kanon api-review alias

[kelos-bot]

What type of PR is this?

/kind cleanup

What this PR does / why we need it:

Wires /kelos api-review as an alias for the existing Kanon reviewer workflow by broadening both reviewer webhook body filters. Updates the Kanon workflow README so it no longer claims Kanon has no API surface, and documents that CLI/config API review is handled by kanon-reviewer.

Adds example coverage for the Kanon reviewer webhook filter so /kelos api-review works on PR comments and submitted PR reviews while /kelos review continues to work.

Key takeaways

• The two Kanon reviewer webhook filters now cover both /kelos review and /kelos api-review, including submitted PR reviews.
• The README now accurately states that Kanon's CLI/config API surface is reviewed by kanon-reviewer and that both commands run the same reviewer.
• The added example test exercises the alias, the existing review command, and the retained bot exclusion.
