[FEATURE REQUEST] Upgrade AdminLTE to v4

[BobbyGoop]

Any thoughts about integrating with AdminLTE version 4? I know there was a merged PR for updating Bootstrap to 5.* and AdminLTE to 3.2.0, but they are not officially compatible, and there are bugs like in #642

I tried upgrading myself just by replacing the CSS and JS files with the new ones, but it doesn't work—Bootstrap SCSS isn't loading. So, it would be great to at least make the front-end part of Jazzmin less outdated
