Update steps

The following instructions are for updating from 4.5.16.

If you are upgrading directly from an earlier release, please carefully read the upgrade notes for the skipped releases as well, as they often require extra steps such as database migrations. In particular, it is very important to read the 4.5.0 release notes.

1. Restart all Mastodon processes.
