Migrate to Bootstrap 5 / Fedora Bootstrap 2

[ryanlerch]

This migrates the base templates, and the FAS, Centos, and Default themes to use Bootstrap 5 / Fedora Bootstrap 2 (which uses Bootstrap 5)

A few things have changed between majopr versions of boostrap, but the main things we had to migrate here were:

• left and right margin / padding / text alignment utilities now use the start and end terminology.
• data-* attributes that bootstrap 4 used to enable javascript things now use the data-bs-* prefix
• form-groups are no more -- we just use the padding utilities for these now
• finally, bootstrap 5 doens't need jquery anymore. We still have to include it as we use it elsewhere, but ideally we migrate that code in the future so we arent using jquery anymore.
