Use Template String Literal Type for ApplicationCommandData.name

Is your feature request related to a problem? Please describe.

The discord API outlines the requirements of slash command names:

Command names must be lower-case and match the regular expression ^[\w-]{1,32}$. Commands (including sub-commands) with upper- or mixed- case names will be rejected by the API with a HTTP 400 (Bad Request) response.

It would be nice if this was type checked beforehand, to prevent invalid request errors later.

Describe the ideal solution
A clear and concise description of what you want to happen.

Template string literals could be used to enforce the format of the string.

Runtime regex assertions, but that's runtime.

I don't believe TypeScript supports regular expression type literals yet, so I'm not sure how we could achieve this. At most, maybe Lowercase<string>?

Disregard - that's only for converting string literals.

yeah it looks you're correct they a discussion about it here, but nothing has come of it.

As we currently cannot really do anything about this, I will close this issue.

We can revisit this whenever there is a possible way of doing this.
