Flask version parsing not compatible with prereleases

[ThiefMaster]

  File ".../env/lib/python3.9/site-packages/sentry_sdk/integrations/flask.py", line 71, in setup_once
    raise DidNotEnable("Unparsable Flask version: {}".format(FLASK_VERSION))
sentry_sdk.integrations.DidNotEnable: Unparsable Flask version: 2.0.0rc1

sentry-python/sentry_sdk/integrations/flask.py

Line 69 in 927903e

version = tuple(map(int, FLASK_VERSION.split(".")[:3]))

This assumes the version number only contains digits, so anything else that's valid in a Python version breaks the check.

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!

not a problem atm since flask isn't in rc phase but not stale since it would break again in case of a future update that includes beta/rc...
