George Kalpakas e9cb0454dc feat(upgrade): more closely align UpgradeModule#bootstrap() with angular.bootstrap() (#46214)
Previously, [UpgradeModule#bootstrap()][1], while being a replacement
for and accepting the same arguments as [angular.bootstrap()][2], did
not return the same value as `angular.bootstrap()` (i.e. the AngularJS
injector in most cases). This made it less straight forward to migrate
some usecases that relied on the return value of `.bootstrap()`. The
work-around was to access the injector via [UpgradeModule#$injector][3]
(after the app had been bootstrapped with `UpgradeModule#bootstrap()`).

This commit addresses this by ensuring `UpgradeModule#bootstrap()`
returns the same value as `angular.bootstrap()`, making it easier to
replace the latter with the former.
