[libc++] remove minor version in status pages (#113241)

Minor version of releases starts at `N.1.0` for all releases since 4532617.

The current status pages are not terribly wrong (the version during
development can be considered `N.0`), but still it's kinda weird to use
versions that never get released as the lower bound.
