ReferencingFormatTest failing with newer versions of PROJ (9.5.0+)

[WouterVisscher]

I noticed that the ReferencingFormatTest is failing when a newer version of PROJ is used. (anything 9.5.0 or newer)
The test fails on the testParser() the expected warning is not return.

It seems to be related to a change in the PROJ code -> https://github.com/OSGeo/PROJ/pull/4108/files
This warning is now been treated as a grammar_error (which seems logical)

They also identified it as a potential issue.

(removing backport label. As it moves reports on the C++ API from WKTParser::warningList() to WKTParser::grammarErrorList(), it is not fully backwards compatible)

Issue (as far that I can see) is that fixing this might bring complication issue. Simply adding

                 }
                 break;
             }

Would fix it, if newer versions of PROJ are used. But will break anything older than 9.5.0.

I tried making the ant build proces aware which version of PROJ is used and apply a patch, but that didn't feel right...
So I'm not sure if this can be fixed without breaking changes.

hello @WouterVisscher is this issue still open and if it is then can you assign this task to me

Given that PROJ 9.5 was released one year ago, it seems fine to me to make it a requirement and apply the proposed change unconditionally (without trying to make the ant build version-aware).
