DOC: clarify see also for DataFrame.iterrows()
changed ` .x()` to `Dataframe.x()` in See Also for DataFrame.iterrows.
@sameshl sorry, I just merged https://github.com/pandas-dev/pandas/pull/27893, another PR that fixed the same issue. Because it was their first contribution, I merged the other one, but still, thanks a lot for your contribution, and sorry I didn't merge it.

BTW, one thing you can do to prevent this to some extent is to include a `closes #27862` (with the issue number) in your PR. Then at least that shows up as a referenced PR in the issue, and other people that want to work on it might see that. You are also always welcome to explicitly mention on the issue that you are working on it. @jorisvandenbossche No problem! I should have included the issue number in my PR. :sweat_smile:
Giving beginners a chance should be the priority anyway. Thanks!
