Doc: gpkg "Performance Hints" link broken

[pedros007]

What is the bug?

The Performance Hints link on the gpkg driver should go to the sqlite driver. However, it's broken.

Steps to reproduce the issue

1. Load gpkg configuration options documentation
2. Scroll to the section OGR_SQLITE_CACHE and OGR_SQLITE_SYNCHRONOUS, which says

see Performance hints.

3. Click Performance Hints and the #target-drivers-vector-sqlite-performance-hints does not exist on gpkg.html so nothing new is displayed.

The link goes to a target on gpkg.html. However, the target should link to the sqlite.html at https://gdal.org/drivers/vector/sqlite.html#target-drivers-vector-sqlite-performance-hints

Additional context

I think the problem is the way the restructured text sets a CONFIG on the sqlite docs:

https://github.com/OSGeo/gdal/blob/5481008668c818303c2b429b53860a2d787c189b/doc/source/drivers/vector/sqlite.rst?plain=1#L458-L464

and is referenced by the gpkg docs: https://github.com/OSGeo/gdal/blob/5481008668c818303c2b429b53860a2d787c189b/doc/source/drivers/vector/gpkg.rst?plain=1#L492-L494

You probably need an absolute link to the sqlite rather than relative... but I don't know how to make the change in a way that preserves cross-page reference in all cases.
