Import Callable from collections.abc

[cyyever]

What does this PR do?

Python 3.10 has moved Callable to collections.abc

[Rocketknight1]

@cyyever will this break Py3.9? We might pause merging it for a couple of months until Py3.9 reaches EOL in that case.

[cyyever]

@Rocketknight1 We have switched to Py3.10

[Rocketknight1]

We've switched in the CI, but I don't know if we're intentionally breaking Py3.9 support yet! cc @ydshieh are we officially dropping it now? We might want to update the frontpage README in that case

[cyyever]

@Rocketknight1 Yes, we can delay it.

[cyyever]

@Rocketknight1 @ydshieh EOL of 3.9 is Oct 1.

[Rocketknight1]

I guess we can merge this, then! Can you check the CI and ping me once it's green?

cc @ydshieh are we officially dropping it now?

Not officially yet, and I didn't know it's Oct 1.

I got this search result

https://endoflife.date/python

which says it's Oct 31.

and this

https://devguide.python.org/versions/

only mention Oct but not the day.

I would prefer to wait until it reaches EOL and then drop the support on our side.

😂 I was told that it is tomorrow...
