Remove `text-transform: uppercase` from buttons

[caosborne89]

Motivation

All the button text styles are uppercase. It would be useful to add alternatives for each button style that removed the uppercase text-transformation.

Proposed Resolution

Add alternatives for each button style that does not include the uppercase text-transformation.

Updated approach: Update the default appearance of buttons to not include text-transform: uppercase, and include the change as part of the next minor release of AZ Bootstrap. We should also backport to 2.x.

Sentence case is what Bootstrap uses by default: https://getbootstrap.com/docs/4.6/components/buttons/ https://getbootstrap.com/docs/5.2/components/buttons/

Even if options are added, and a new class created, perhaps there should be consideration about changing the default off of all caps.

Bringing over some relevant notes from the conversations on this thread: https://uarizona.slack.com/archives/C0SAW6H4J/p1719869500798899

• We'd like to change the default behavior but felt that was a change that probably necessitates a minor/major version bump of Arizona Bootstrap (which is something we haven't really done so far).
• Should coincide with the release of AZ Quickstart 2.12.
• Still need to decide how best to merge this change into AZ Bootstrap, but PR should be made against main branch (where all 5.x changes are too).
• How to include that change into AZBS 2.x release (based on Bootstrap 4.x) will be a more complicated thing we'll need to figure out.

I will update the ticket description based on this information.

Backporting to the 2.x branch sounds like a good idea, too.
