Add support for text-field buttons

[devmike123]

I mean that when a button named "Nickname" is clicked, in the text box it will show a label like:- nickname: <text to be written, where we can simply write the text and the command gets executed i.e. the nickname of user changes to that text.

Even slash commands support writing text, but as they're still being improved and there are frequent issues with it like Discord API outages.
