Docs: Fix the way tabs are declared

Since python doesn't have a way to lock deps for a particlar project
by default, I didn't bother with it. This resulted in mkdocs updating at
some point, bringing a breaking change to how tabs are declared and
broken tabs on docs-develop.pleroma.social. I've learned my lesson
and locked deps with pipenv in pleroma/docs!5. This MR updates Pleroma
docs to use the new tab style, fortunately my editor did most of it.

Closes #2045

 Replaces embedded objects with references to them in the `objects` table. Only needs to be ran once if the instance was created before Pleroma 1.0.5. The reason why this is not a migration is because it could significantly increase the database size after being ran, however after this `VACUUM FULL` will be able to reclaim about 20% (really depends on what is in the database, your mileage may vary) of the db size before the migration.

 RUM indexes are an alternative indexing scheme that is not included in PostgreSQL by default. You can read more about them on the [Configuration page](../configuration/cheatsheet.md#rum-indexing-for-full-text-search). They are completely optional and most of the time are not worth it, especially if you are running a single user instance (unless you absolutely need ordered search results).
