Change assumed end of season date from November 1 to November 30

[TK2575]

While introducing/familiarizing myself with this repo I noticed a few places where the assumed end of season was no later than November 1st. We've had a few World Series in recent memory end a few days after the 1st. I figured adjusting this to end of month would be a good first issue opportunity.

Thanks for the contribution. LGTM

I had a worry that the scraped page was only regular season stats, so I checked with and without for 2022 and it is, in fact, including postseason so we should extend it to end-of-November:
