Upgrade all pip dependencies to their latest versions (#1532)

Part of https://github.com/tiny-pilot/tinypilot-pro/issues/1002,
~stacked onto [the Python 3.9
upgrade](https://github.com/tiny-pilot/tinypilot/pull/1531)~ (merged).

This PR upgrades all pip/Python dependencies to their latest version,
following our [new guide for that
process](e845e1165b/CONTRIBUTING.md (L187-L201)).
A few notes:

- According to their changelogs,
[`Flask`](https://flask.palletsprojects.com/en/2.3.x/changes/),
[`Flask-WTF`](https://flask-wtf.readthedocs.io/en/1.1.x/changes/), and
[`eventlet`](http://eventlet.net/doc/changelog.html) should be safe to
bump to their latest versions.
- With `eventlet`, it’s slightly strange, since according to their
[changelog the latest *documented* version is
0.33.0](https://eventlet.net/doc/changelog.html), but the [latest
*available* version is
0.33.3](https://github.com/eventlet/eventlet/tags). We also *have* to
use [0.33.3, due to this
bug](https://github.com/eventlet/eventlet/issues/781) – 0.33.0 doesn’t
work with Flask, it wouldn’t even start the app due to an import issue.
- [`PyYAML`](https://pypi.org/project/PyYAML/) was already up to date
(at 6.0.1)
- `monotonic` and `typing_extensions` no longer appear as indirect
dependencies, so I have removed them from the license page
- `dnspython` is a new indirect dependency, but for some reason [we
already had it listed on our license
page](e845e1165b/app/license_notice.py (L111-L115))
- `blinker` is new as well

It would be cool if you could QA this PR on your end.
