Add `word-wrap` and `word-break` to Reboot

Created by: leafac

Why would you want the default browser behavior of a long word overflowing the container?

What’s already done:

• Applied .text-break to body in Reboot (see https://getbootstrap.com/docs/5.0/utilities/text/#word-break)
• Removed instances of word-wrap from components, which now became redundant.

What’s left to do:

• Remove .text-break?
• Provide an utility with the converse, which sets word-break and word-wrap back to normal?
