Type hint bug in solara.use_thread

[ntjess]

solara/solara/hooks/use_thread.py

Line 18 in ae99741

callback=Union[

should be:

- callback=Union[
+ callback: Union[

Otherwise type checkers complain.

Oh man, this solves a long standing mystery that type inference never worked with use_thread!

Great catch.

Happy to help! Fun fact -- it was identifiable since pyright recently began correctly treating unions on RHS as values instead of hints: microsoft/pyright#7416 (comment)

So there was a strange interplay between union-ness and value-ness until now
