correct redirections in doc/redirect.csv for rolling
- [x] closes #31762 

@WillAyd I tried and found other rolling related links broken too. So, I have changed other rolling related redirections too. Sounds good. Is the sphinx build generating warnings about these links perhaps? Wondering if there is a way to identify more thanks @rushabh-v  We also need new redirects from `/pandas.core.window.Rolling...` to `pandas.core.window.rolling.Rolling...` to fix the actual issue reported by @WillAyd (so reopened the issue) Sure, will be opening a PR soon :) Sorry @jorisvandenbossche I couldn't figure out what you did mean by,

Can you please elaborate a bit more? @rushabh-v check the two links mentioned y @WillAyd in the original issue: https://github.com/pandas-dev/pandas/issues/31762 The first link should redirect to the second.
