Ruff rules UP for pyupgrade

[cclauss]

Make all of ruff's pyupgrade rules mandatory in pre-commit.

This pull request makes the minimum Python v3.10, which matches the default Python of the oldest Standard Support Ubuntu LTS as recommended at:

• Tools: add CODING_STANDARDS.md consolidating style rules ardupilot#32453 (comment)

Related to:

• Vagrantfile: Add Ubuntu 24.04 LTS noble and 26.04 LTS resolute #7551

conflict with #7554, #7555, #7552 need wait

I'm OK with this PR except for the enforced upgrade.

Not saying we can't do it, but not part of a general other PR and not without general agreement.

I'd like to have minimum Python version the same for both the Wiki and the normal firmware, just for the simpler story.

Set tool.ruff.target-version = "py38"

Used from __future__ import annotations to allow EOL Python 3.8 to use modern type hint syntax.

[peterbarker]

OK, so this looks good. How was it tested?

I'm a little concerned about

... so I'd like to know that this was actually tested on 3.8

Why are you concerned about from __future__ import annotations on legacy Python 3.8?

% uvx python3.8 # https://docs.astral.sh/uv

Python 3.8.20 (default, Oct  2 2024, 16:12:59)
[Clang 18.1.8 ] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from __future__ import annotations
>>> d: dict | list | None = {key: value for value, key in enumerate("abcdefg")}
>>> d
{'a': 0, 'b': 1, 'c': 2, 'd': 3, 'e': 4, 'f': 5, 'g': 6}
>>> type(d)
<class 'dict'>
>>> __annotations__
{'d': 'dict | list | None'}

Without uv, this could be tested on legacy Python 3.8.10 with:
% docker run -it ubuntu:20.04
# apt update ; apt install -y python3 ; python3
