DOC: Multi-conditional examples added to .loc docstring
- [ ] closes #53546 

Adds two examples of using `.loc` with multiple conditions and links to Boolean Indexing [user guide](https://pandas.pydata.org/pandas-docs/dev/user_guide/indexing.html#boolean-indexing).

NOTE: I was unable to get the documentation to build on my computer so I could not view the changes before opening this PR. I will have to view them by trying the `/preview` comment.

Also please ensure you are running pre commit on your code changes https://pandas.pydata.org/pandas-docs/dev/development/contributing_codebase.html#pre-commit Thanks @sweisss
