chore: bump agent config schema version

[github-actions]

Auto-generated bump PR.

Bump computed from the schema diff since v13.6.1.

⚠️ Release ordering

Merge this PR BEFORE cutting the release tag.

If the release tag is cut before this PR merges, the tag's
configurationDefinitions.yml will still reflect the
pre-bump version even though the schema itself reflects the
new keys. Consumers see a mismatch.
