Add support for reading User.pronouns

[duccdev]

Which package is the feature request for?

The core library

Feature

ClientUser (the selfbot) has a readable pronouns property while a normal User doesn't
I'm trying to make my own little AI selfbot kinda like Clyde using this and I wanted to give the model some info about the user and unfortunately I can't read pronouns

Ideal solution or implementation

Add a pronouns property to User that can be accessed using User.pronouns
For example: msg.author.pronouns
