Add 'table' as Allowed `orient` Value in to_json Docs

[WillAyd]

Right now the allowed values for Series and DataFrame objects are missing table as an allowed value for the orient parameter in to_json

Is it? Am I missing something?

[WillAyd]

Yep - look a little further up in your screenshot at the subsection for Series and DataFrame.

Very minor / nuanced but good to clean up for consistency

@WillAyd I have added 'table' as allowed orient Value in to_json Docs. Could you please review my PR and let me know if I have to make any changes.
