[9.x] Update Bootstrap pagination style

[jrd-lewis]

Rebase of #36467 onto the master branch instead the 8.x branch.

This PR updates Laravel's built-in Bootstrap pagination (bootstrap-4.blade.php) to be styled similarly to the built-in Tailwind pagination (tailwind.blade.php).

@driesvints @GrahamCampbell Based on the earlier conversation, should I update the Bootstrap 3 pagination too?

@jrd-lewis let's see what Taylor says first.

While I appreciate the effort - I'm not sure the breaking change is worth it. Users can already export these views and customize them how they wish. If we do this it could potentially break people's frontends when they upgrade.

@driesvints @taylorotwell With laravel/ui#212 being merged into the Laravel/UI package should we revisit this PR or perhaps start a new PR to register it as being specific to Bootstrap 5 pagination?

[driesvints]

@jrd-lewis it seems Taylor doesn't wants to do the breaking change but indeed maybe with that PR it's different now. I'd attempt it again to see if he might merge it now. Try sending it in to 9.x?
