Refine Jira issues list page

Closes #223917

See merge request gitlab-org/gitlab!36520

The feature flags `vue_issuables_list` and `jira_integration`
should not be tied together, i.e. we should be able to
enable just `jira_integration` and it should work without
the need to enable the other feature flag.

This change makes sure the frontend considers this and
still renders the Jira issues list when the ff is enabled.
