feat: add ability to use ionicons as icon font

### Describe Problem

When viewing the latest cheatsheet for ionicons, there is no glyph that one can copy and paste like fontawesome does in their cheatsheet...

Example from fontawesome:

### Describe Preferred Solution

I would like to see an option to copy the glyph character in the cheatsheet found on:
https://ionic.io/ionicons

### Describe Alternatives

_No response_

### Additional Information

A reason I want to have this, is for whenever I have ionicons installed on something like my operating system, I'd be able to just copy and paste them into text editors and document editors.

Apparently version 2 of ionicons had this in the cheatsheet. But then I'd have to download the exact same version ionicons TTF font. This doesn't count for the latest cheatsheet.
