Feature request: Add Bootstrap Icons Page

[tacman]

Can you add a page for the new bootstrap icons please?

Also, it'd be nice to see a "best practices", or samples of how to include all icons (probably not the best practice) or individual icons. Out of laziness, I frequently include all the fontawesome free icons, but that does lead to a pretty large file. I'd like to move over to using the bootstrap icons by default, mostly to have one less dependency.

@tacman we've decided to use the http://heroicons.dev/ icon library (which is SVG powered). I'll make sure to create a documentation page for multiple icon libraries that can be used (BS icons are awesome too!).
