Add samples for listing table.files and table.partitions

Question

After examining your documentation, I couldn't locate the methods to list a table's partitions or its data files. Could you please provide relevant examples or consider adding this capability if it's not currently available?

Hey @moryachok Thanks for raising this. This is currently being worked on in #511

The files one should be rather straightforward since that's also supported through the CLI: pyiceberg files database.table

@moryachok It looks like someone else is already working on files, how about partitions? I'll merge #551 later today and then it should be relative straightforward.

Hey @Fokko,
that would be awesome, let me know when it merged and I will test it on my side.
