PyScript Stub Generation Errata

[gauravmm]

I'm working with the PyScript type stubs right now and am logging the errata I spot:

1. _timer_state.start and _timer_state.change: parameter duration should be str | int
2. Almost all static methods that accept entity_id: entity_id should be str | list[str] | tuple[str]
3. _input_number_state should be ConvertibleToFloat. I don't know how best to implement this.
4. remote.send_command, _remote_state.send_command : parameters delay_secs, hold_secs should be float
5. task.wait_until: the default value of webhook_methods: ["POST", "PUT"]
6. event_trigger: parameter str_expr should be str | None
7. color_name parameters should have a type defined once and re-used.

8. str_expr in state_trigger decorator stub should take str, list[str] and set[str] as types.

I opened PR #817 to fix that.
