fix(ci): include v prefix in release_version output for Ketryx

Ketryx version names start with "v" (e.g. v1.3.0), but the
get-release-version step was stripping it by capturing only the
part after "v" in the regex match. This caused the version passed
to the Ketryx compliance check to be bare semver (e.g. 1.3.0).
