Comment 1 for bug 2000482

WIP branch:

https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/berick/lp2000482-angular-15-bootstrap-5

To use:

cd Open-ILS/src/eg2 && rm -rf node_modules
sudo npm install -g @angular/cli@^15.0
npm install

The upgrade to Angular 15 is done in the WIP branch. The Bootstrap migration will take some work, though.

Bootstrap changes I've encountered so far mostly have to do with changing utility class names, e.g. ml-2 is now ms-2 ("margin left" vs "margin start" for better RTL support), loss of "form-inline" class and way more flexibility with the grid system.

This is a good reference: https://getbootstrap.com/docs/5.0/migration/
