Inlay hints of the resolved version from pubspec.lock

[SunlightBro]

Describe the use-cases of your feature

Especially with a lot of packages that need to resolve their transitive dependencies,
it's not always useful to force the latest version of every package.

So it would be awesome to show the actual resolved version of a dependency in side the pubspec.yaml as an Inlay hint

(Additional)
If the resolved version in the pubspec.lock is already the latest, maybe don't show the
Hint/Quick Fix to "Update package"

Describe your solution

Either inspecting the the existing pubspec.lock,
or if that does not exist yet run dart pub upgrade -n
