Rename DataFrame.where to DataFrame.filter?

[MarcoGorelli]

Is your feature request related to a problem? Please describe.

The following libraries use DataFrame.filter:

• Polars
• Ibis
• PySpark (though they also have where as an alias)
• DuckDB in their relational api (https://duckdb.org/docs/api/python/relational_api.html#filtercondition)

Renaming DataFrame.where to DataFrame.filter (or at least introducing a filter alias?) might lower the learning curve?

Cool -- would love to take a contribution here if you'd like!

I think we're open to exposing an alias and just forward the *args and **kwargs to .where.
