fix(ci): resolve validate-version output in release-lfx changelog link (#13610)

The create-release job references
needs.validate-version.outputs.current_version in its generated release
notes (the Full Changelog compare link), but validate-version was not in
the job's needs array, so the expression evaluated empty and the link
rendered as compare/v...lfx-vX.Y.Z (broken base).

Add validate-version to the create-release needs. This adds no real
serialization: create-release already waits on release-lfx, which
transitively requires validate-version via run-tests, and the job's
always() if-condition is unaffected.

Flagged by actionlint: property "validate-version" is not defined in
object type {build-docker, release-lfx}.
