debugger: Use current worktree directory when spawning an adapter (#31054)

/cc @osiewicz 

I think bringing this back should fix **bloveless** his issue with go
debugger.
This is also nice, so people are not forced to give us a working
directory, because most adapters will use their **cwd** as the project
root directory. For JavaScript, you don't need to specify the **cwd**
anymore because it can already infer it

Release Notes:

- debugger beta: Fixed some adapters fail to determine the right root level of the
debug program.
