FIX: Move downloading of Maxmind databases to after assets:precompile (#28157)

We have been seeing `ZLib::BufError` when running the `assets:precompile` rake
task.

```

```

The hypothesis here is that some thread unsafe issue is causing the
problem since we download the Maxmind databases in a thread and run
decompression operations once the gzip file is downloaded.

In the near term, we plan to move downloading of Maxmind databases out
of the Rake task into a scheduled job so this patch should be considered
a temporary solution.

The trade-off here is that build time will slightly increase since we
are not longer downloading Maxmind databases while precompiling assets
at the same time.
