[ENH] Move the linting standards to match `py310`

[phoeenniixx]

Is your feature request related to a problem? Please describe.
The current codebase follows the older py39 target version in ruff configuration. Since the project now officially supports Python 3.10 and above, we should move to the target version to py310

Hey @phoeenniixx, can I work on this task?

Hi @phoeenniixx! I'd like to work on this.

I investigated and found that while target-version = "py310" was already set,
the UP (pyupgrade) ruleset had 440 violations across the codebase that hadn't
been applied yet. I also found deprecated top-level ruff config keys.

PR: #652
