DOC: pd.DataFrame.align() join parameter values are insufficiently explained

[FlorinAndrei]

Pandas version checks

• I have checked that the issue still exists on the latest versions of the docs on main here

Location of the documentation

https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.align.html

Documentation problem

For the join parameter, only its values are mentioned. But what do the different values do? The current documentation provides no clue.

Suggested fix for documentation

Please explain what the different values of the join parameter do.
