Fix resource calls

[mcebria-hg]

The calls to resources don't work, I have adapted them according to geoserver documentation and performed the call tests.

Thanks for your contribution!
Could you add a small line about this change in the CHANGELOG.md file too?

[mcebria-hg]

Done, it's ok?

[arthurdjn]

I added some reviews in your tests, otherwise everything looks good !

[mcebria-hg]

I don't know why test_head_resource breaks, I run tests on my machine with a geoserver v2.23 and it works great.

If you prefer we can delete it and set with "Not implemented yet" or we try it without path.

If test_get_resource works, test_head_resource should work .

[arthurdjn]

There are two errors: one due to test_head_resource the other from test_delete_resource

I agree that for now test_head_resource can be skipped, I think that the documentation from geoserver is not up to date

[arthurdjn]

I think something like the below is easier to read:

assert data is True

WDYT?

This test is problematic because it will delete the fixture test_coverage, and the fixture teardown will break (because it will try to remove an already deleted coverage).

Instead I would suggest to upload a tmp coverage, and then delete it within the test.

def test_delete_resource(test_geoserver: GeoServer, test_workspace: str) -> None:
    coveragestore = "tmp-coveragestore"
    file_path = Path(TEST_DATA_DIR, "rasters", "raster.tif").resolve()
    test_geoserver.upload_coverage_store(
        file=file_path,
        name=coveragestore,
        workspace=test_workspace,
        format="geotiff",
    )
    
    path = f"data/{test_workspace}/{coveragestore}"
    msg = test_geoserver.delete_resource(path)
    # ...
