* Remove `skip-stale-issue-message`.

This was removed in version 4.0.0 of the action, along with `skip-stale-pr-message`. A lack of setting this option is now the same as setting `skip-stale-issue-message` to `true`.

See https://github.com/actions/stale/releases/tag/v4.0.0.

* Update inline comment noting action version.

* Apply 6.0.1 update.
