Does irsa.query_region work with vector SkyCoords?

I'm having trouble getting irsa.query_region working with a vector of SkyCoords. Here's a MWE

```Python
from astroquery.ipac.irsa import Irsa
from astropy.coordinates import SkyCoord
import astropy.units as u

coord_vector = SkyCoord(ra = [58.8, 179.8]*u.deg, dec = [14.6, -52.7]*u.deg)
results = Irsa.query_region(coordinates=coord_vector, spatial='Cone', catalog='catwise_2020', radius=0.5 * u.arcmin)
```
Produces:
```Python
Traceback (most recent call last):
File "", line 1, in
results = Irsa.query_region(coordinates=coord_vector2, spatial='Cone', catalog='catwise_2020', radius=0.5 * u.arcmin)

```

Start with astroquery/ipac/irsa/core.py and run the Python MWE from the issue to inspect the query_region path for vector SkyCoords. Check the generated ADQL and the resulting TAP request, then verify that querying multiple coordinates no longer produces the reported invalid-query error.
