⭐ Suggestion

When I drag and drop a file from VS Code's explorer into the top of my TypeScript code, it should insert an import statement

For example if I have the workspace:

index.ts
sub/
    other.ts

And I drop other.ts into index.ts, it should insert:

import $1 from './sub/other'; // here $1 is where the cursor should be after the drop

Other cases

• I should be able to drag and drop multiple files to create multiple imports

• Possible: If I drop the file into somewhere else in the file, we should instead insert an import expression

• The added import path should take into account TypeScript's path resolution logic

• This also should apply when copy and pasting a file into the editor

Related is #50187, but I guess is not the same. I suppose this needs a custom TSServer command?
