datetime.datetime.utcnow() is deprecated

[grigi]

Problem Statement

Python 3.12 deprecated datetime.datetime.utcnow():

.pyenv/lib/python3.12/site-packages/sentry_sdk/tracing.py:148: DeprecationWarning: datetime.datetime.utcnow() is deprecated and scheduled for removal in a future version. Use timezone-aware objects to represent datetimes in UTC: datetime.datetime.now(datetime.UTC).

Solution Brainstorm

Update sentry to use datetime.datetime.now(datetime.UTC) instead of datetime.datetime.utcnow() as suggested.
Some quick testing shows that for this to work on python < 3.11 would have to do datetime.datetime.now(datetime.timezone.utc) instead as the datetime.UTC shortcut was only added in python 3.11

Good catch @grigi! I've added this to the list of things we should tackle in order to support 3.12.

If you or anyone reading this feels like it, PRs are very welcome!

I made the changes, but unfortunately, realized after that I could not push the code to a new branch. What is the process to open a PR?
