In order for the new star difficulty to be shown to users on the next
release.
catch's difficulty calculator version is not bumped because the only
catch change pending deploy is https://github.com/ppy/osu/pull/28353 and
that affects performance points only.
A `false` value marks the user as being on the latest release, and
notifies them as such when clicking the button in settings. In reality,
we don't know whether this is the case yet - we're just deferring the
check.
Somewhat minor change because the chance of a user manually going into
settings and clicking the button is very small.
