Increase allowed import time for Python 3.12/3.13 to 265

[bdraco]

I ran a profile of the imports and did not find any one thing that was causing the import time to jump up. The bulk of the time outside of bootstrap is spent in typing.py, and since we do not want to discourage adding more typing it seems like we need to increase this.
