Update steps

The following instructions are for updating from 4.5.9.

Non-Docker

[!TIP]
The charlock_holmes gem may fail to build on some systems with recent versions of gcc.

1. Install dependencies with bundle install and yarn install --immutable
2. Precompile the assets: RAILS_ENV=production bundle exec rails assets:precompile
3. Restart all Mastodon processes.
