Add a 1st, 2nd, 3rd etc. option to custom date format

[spiritually-soup]

Currently the date options are 1, 01
I understand it might be difficult because it's not a numeric value, but if possible, it would be fantastic if we can have a 1st, 2nd, 3rd option!

My config is currently set in the style Monday, 1 Nov but without the 1st it just isn't right to my brain somehow 😅
