test GDAL 3.7.2

[visr]

This in turn allows GDAL 3.7.2, which requires PROJ_jll v901 (which is PROJ 9.3).

I want to see about downstream failures.

[visr]

Some breakage on ArchGDAL, and the Rasters downstream test is failing because Rasters doesn't have GDAL as a direct dependency and therefor no compat set? @rafaqz this should be possible right? Otherwise, I guess it's also not terrible to add GDAL as a direct dependency as well.

[rafaqz]

Yeah I can add a direct dep, more correct than using ArchGDAL.GDAL anyway

[visr]

Yeah it'll probably be a while before ArchGDAL is pure-julia and can drop the GDAL dependency.

I'll release this version, which allows both old and new GDAL/GEOS/PROJ versions, as a patch release. This to unblock some issues using the wrapper packages together, like JuliaGeo/LibGEOS.jl#182 (comment).

Then I will wrap the new functions from GDAL 3.7. Wrapping those functions means I need to drop support for GDAL 3.6 since it won't have those methods, which means it is also dropping support for PROJ < 9.3. This shall be tagged as a new minor release.
