​Reduce external dependencies with self-hosting

[fingerart]

Description

Can I use sqlite instead of Postgre or redis in self-hosting? In some cases, I don't want to rely on external components and don't have particularly high requirements for performance. It's a bit like gitea, I can choose not to use MySQL and PostgreSQL.

sqlite is lacking some features we dependent on postgresql. we would provide an all-in-one image including all dependencies without further components management.
