Rails 7: ComparisonValidator

Everyone who has worked or is working in the Rails ecosystem will recognise the piece of code in the code snippet.

I am talking about the custom validator method #end_date_is_after_start_date. Before Rails7, there was no inbuilt validator present for such a use-case.

Rails 7 added 𝐂𝐨𝐦𝐩𝐚𝐫𝐢𝐬𝐢𝐨𝐧𝐕𝐚𝐥𝐢𝐝𝐚𝐭𝐨𝐫, and it provides a lot of comparison options like 𝚐𝚛𝚎𝚊𝚝𝚎𝚛_𝚝𝚑𝚊𝚗, 𝚐𝚛𝚎𝚊𝚝𝚎𝚛_𝚝𝚑𝚊𝚗_𝚘𝚛_𝚎𝚚𝚞𝚊𝚕_𝚝𝚘, 𝚎𝚚𝚞𝚊𝚕_𝚝𝚘, 𝚕𝚎𝚜𝚜_𝚝𝚑𝚊𝚗, 𝚕𝚎𝚜𝚜_𝚝𝚑𝚊𝚗_𝚘𝚛_𝚎𝚚𝚞𝚊𝚕_𝚝𝚘 and 𝚘𝚝𝚑𝚎𝚛_𝚝𝚑𝚊𝚗.
