Improve Priviledged Intents description

[Andre601]

I think the descriptions for the priviledged intents on the developer portal could require some Tweaking, to make it more clear, if you need it for your bot or not.

The descriptions should perhaps provide some common cases, where this intent would be required to have.

Example with Member Intent (assume the markdown being formatted on the site):

If your bot tracks server members or downloads the entire member list, you may need the server members intent to receive member events and the member list.  
This is often the case for things like listening for members joining or retrieving Member-specific information (i.e. getting the nickname).

**NOTE: This may limit your bot to 100 servers in the future. [Read more here]({link})**

Agreed! More clarification would help.
