internal/releasetargets: drop 1.21 targets, add 1.24 targets

The Go 1.21 entries are no longer needed now that go1.23.0 is out.

The list for tip is the same as for Go 1.23, except that the windows/arm
port is not included because it's currently marked broken (CL 601777).

I considered renaming allReleases to something more appropriate since
it tracks only first class ports now, but leaving that to a future CL.

For golang/go#40561.
For golang/go#68552.
