Fetch and display CHANGELOG.md while selecting version of dependency as documentation

Describe the use-cases of your feature

When deciding whether to update a package now. It's useful to check what has changed since the version you have.

Describe your solution

It would be cool I one could fetch and display CHANGELOG.md while selecting the version of a dependency when you try to open the documentation.

On MacOS:

1. Move cursor to version of dependency

dev_dependencies:
  flutter_test:
    sdk: flutter
  lint: ^1.1[cursor here].1

2. Press F1
3. Show a dropdown with the CHANGELOG.md, just like you display the README.md for the documentation of a package
