allow setting the cursor

Exposes style.cursor of the DOM element so that it can be changed. Tested with wgpu RFB canvas too.

LGTM but needs an update with main to get that lint error resolved.

Run flake8 .
./tests/test_widget.py:214:5: B017 assertRaises(Exception) and pytest.raises(Exception) should be considered evil. They can lead to your test passing even if the code being tested is never executed due to a typo. Assert for a more specific exception (builtin or custom),

It's interesting how flake8 tells us how to use pytest. On the other hand, it's a very good point.
