Docs are missing info about configuring for SQLite

[raddevon]

Describe the bug
The docs appear to have a page about every supported database engine except for SQLite at Portabase Agent > Databases.

Additional context
I looked for a documentation repo or documentation within the other repos so I could contribute this, but I didn't find either. Forgive me if I've overlooked them.

For any user who finds this in the interim, I found that the critical JSON property for SQLite databases seems to be path.

Here's an example configured SQLite database:

    {
      "name": "SQLite database",
      "type": "sqlite",
      "path": "/databases/my-sqlite-database.db",
      "generated_id": "<your-generated-uuid>"
    }
