fix: Allow double and float types to be rollupable

- We had this restriction in the UI, but the engine can actually handle it
- Tested with doubles, floats
- Tested with the following tables:
```python
from deephaven import empty_table

doubles = empty_table(1_000_000).update_view(["Group = i*10.4", "N = (i % 347)*0.1", "M = (i % 29)*10.2", "Value=i*2.4", "Weight=i*4.2"])
floats = empty_table(1_000_000).update_view(["Group = i*10.4", "N = (float)(i % 347)*0.1", "M = (float)(i % 29)*10.2", "Value=(float)i*2.4", "Weight=(float)i*4.2"])
```
- Updated e2e tests and unit tests
