3.9 and 3.10 seems to have failed after getting a bunch of 403s, will try again tomorrow. Likely due to too many requests being thrown in previous test updates.

for the conflicting files if you check the box in the PR comment it will rebase and resolve those! (I'm doing it now but for future reference that'll fix it)

Tests have passed, experimenting updating opentelemetry as well.
