fix: disable tycho baseline checks in codeql job

which may fail with `VersionBumpRequiredException: Only qualifier
changed for (org.eclipse.lsp4e.<module>). Expected to have bigger x.y.z
than what is available in baseline` despite no actual changes in the
reported module and is actually not required for CodeQL.
