chore(deps): fix Flask syntax error

[ace-n]

This should fix the flaky-bot spam about

TypeError: __init__() got an unexpected keyword argument 'as_tuple'

Note: I have not tested this on App Engine itself; I'm relying on CI to catch any bugs (as they should be easily flagged syntax errors).

Thanks. The problem goes away in Flask 2.0.3, so 2.1.0 works too.

Looks like appengine/standard/migration/storage is flaky.

I suspect a timeout increase might fix that, but I'm not sure how to do that in Python/nox.

@Mariatta @kurtisvg @yuriatgoogle can someone point me in the right direction? 😃

Can we use the @pytest.mark.flaky decorator on the flaky test?

Thanks Ace!

It might be a better idea to merge this as is and address the failing testing in a different issue.

The logs for the failed test are as follows:

err: signal: killed

So it looks like the test itself is passing, but the cleanup is timing out past the time we've allowed each test to run (~30m).

There also seem to be a couple of tests failing lint, which is probably separate issues as well.
