Upgrade to the latest Bootstrap version

[mkArtakMSFT]

There were several breaking changes in Bootstrap 4 (from Bootstrap 3) which we also need to react to as part of this upgrade.

This issue will also be used to track all related work to the bootstrap 5 update:

• identity ui/scaffolding
• project template fixes

I think Bootstrap was past!
By the all recent changes and news in CSS, there is no need for bootstrap.
tying more and more the platform and components to a 3rd party library will add more time and hassle for people who try to make more pure or more customized things.
I believe BootStrap was past though Blazor can be the future.
So if possible while you try to consider the needs of web newbies, consider 1 extra scenario without Bootstrap, Materialize, and font-awesome, Jquery things, which none of them are standards, they may make a buzz for a period and then be gone, and each person can have it's own choice or custom scenario.
So personally I suggest not invest on bootsrap much, just may be there as an option, instead invest more on the standards. Like considering CSS Grid, FlexBox, ...

Met today and we agreed on a plan of record for identity ui for 6.0:

• Both V4/V5 pages and assets will again live in the identity UI package, just like before with V3/V4
• We will need to come up with a new page model convention to make this work (will sync with @pranavkm )
• For 7.0 we can revisit and see if we can switch to UI.Bootstrap5/BootstrapX dlls but too risky to change this late for 6.0

Bootstrap 5.0.2 has been merged in #34052

Still need follow up PR to add back the ability to switch back to V4

@deepchoudhery we have updated to bootstrap5 for net6.0 by default, can you help identify what changes need to go into https://github.com/dotnet/Scaffolding/tree/main/src/Scaffolding/VS.Web.CG.Mvc/Templates/Identity/Bootstrap4/wwwroot for the scaffolding side of things?

[deepchoudhery]

Yes, I'll add an item to track for 6.0-rc1. I'll follow up soon.

@HaoK just used the updated templates for the first time and noticed a few spacing/margin issues. Are these known and being fixed? e.g.

[HaoK]

Yeah @blowdart just went over them for me, we think its just a matter of removing the form-group, I will have a PR open for this today soon, I'll add you to the review
