Fix: re-enable use of parameters in gcs_to_bq which had been disabled

[mdering]

closes #27842

Add in some missing configuration options to the gcs to bq transfer operator. the 8.5.0 release broke a number of things with this operator, mainly the methods to specify the file delimiter, and the time partitioning option.

CI is failing.

[mdering]

@uranusjr I see why, can you approve it to rerun tests?

Is there something you need from me to rerun this?

Can you please add unit test to avoid regression?

[mdering]

@eladkal yes, I added some tests, and fixed the existing tests

[mdering]

since this passed CI and has unit tests, is there anything else I need to do to get this merged?

[potiuk]
