Core: purge py3.8 and py3.9

[Berserker66]

What is this fixing or adding?

Fixes py 3.8 and py 3.9 by yeeting them.
Fixes Windows 7 support, by no longer supporting it.

I touched HK because I wrote that code, I saw stardew has 3.8 stuff too, didn't touch that. There's a couple more 3.8 marked todos, I left some of them alone as they either go beyond deprecation (redesign/changes) or had a question mark. Once we know what to do with those, I suppose those changes could target this branch and we can accumulate it.

How was this tested?

A bit of generate and webhost, but it's probably too early to broadly test at this time.
I also don't currently know why this fails:

Could you elaborate on what Stardew does / needs to do?

Could you elaborate on what Stardew does / needs to do?

There's at least

Archipelago/worlds/stardew_valley/requirements.txt

Line 1 in ba8f035

importlib_resources; python_version <= '3.8'

Archipelago/worlds/stardew_valley/requirements.txt

Line 2 in ba8f035

graphlib_backport; python_version <= '3.8'

Also maybe these:

Archipelago/worlds/stardew_valley/test/stability/TestStability.py

Line 15 in ba8f035

# Python 3.10.2\r\n

Archipelago/worlds/stardew_valley/data/game_item.py

Line 43 in ba8f035

# FIXME this should just be an optional field, but kw_only requires python 3.10...

I don't currently intend to do anything about this, if github is still using an old version by the time this is ready for merge, we can adjust it then.

@Jouramie Just pinging you to keep you in the loop, you're generally much more aware than me of how these things work

[Jouramie]

Yeah there are a couple of things to clean up in stardew, nothing big.

Is there any reason for us to have the build on 3.10? With 3.8 we had stuff that worked on source but specifically broke frozen but I don't think it's relevant here. I think just moving this up to 3.12 makes more sense since that's what we actually ship and we'll probably want to use this action as part of the "nightly"s

[ThePhar]

Code looks good to me, hopefully that's all of the 3.8/3.9 dependent code.

To be safe, I also pulled and did a quick test of generating, hosting, and running a couple clients and they seem to work fine.
