Pushdown Filter Type BLOOM_FILTER is not currently supported in PyArrow Scans

### What happens?

Hi,

I am running into this error message and am unsure what to do.
```
_duckdb.NotImplementedException: Not implemented Error: Pushdown Filter Type BLOOM_FILTER is not currently supported in PyArrow Scans
```
It seems I can either disable pushdown filtering through joins, or materialize the query before doing my join. I would rather not do either, since it is a lot of data that I am processing.

Reading the source files with a non-pyarrow reader is unfortunately not an option at this time.

### To Reproduce

Unfortunately, I don't really have a reproducer, but I think the maintainers will know what the issue is anyways from the error message. It seems to me that Pyarrow do support bloom filter, but the pushdown is just not implemented?

Start at the PyArrow scan path that emits the BLOOM_FILTER NotImplementedException and investigate how join filter pushdown reaches it. The report has no reproducible dataset or code, so first establish a minimal case using DuckDB 1.5.2 with Python 3.11. Done means the supported PyArrow scan no longer raises this error for the reported pushdown scenario, with behavior validated against an appropriate regression case.
