* Docker: Update files about Docker (#4599)

* Docker: Use cache if files used by `yarn install` was not updated

This patch reduces the number of times to installing node_modules.
For example, `yarn install` step will be skipped when only ".config/default.yml" is updated.

* Docker: Migrate MongoDB to Postgresql

Misskey uses Postgresql as a database instead of Mongodb since version 11.

* Docker: Uncomment about data persistence

This patch will save a lot of databases.
