taskParallelExec does not honor current working directory as set by the commands it is running.

[brad-jones]

Steps to reproduce

$this->taskParallelExec()
    ->process($this->taskGitStack()->dir('/repo1')->checkout('develop')->pull())
    ->process($this->taskGitStack()->dir('/repo2')->checkout('develop')->pull())
    ->process($this->taskGitStack()->dir('/repo3')->checkout('develop')->pull())
->run();

Expected behavior

I expect that the git commands are run inside of /repo1, /repo2 & /repo3

Actual behavior

The current working directory is not changed and thus all 3 commands run in the same folder.

Hint: This is due to vendor/consolidation/robo/src/Common/CommandReceiver.php:[email protected]
or \Robo\Common\CommandReceiver::receiveCommand which could prepend a cd $dir; ...

But also needs to take the other public methods in advance (e.g. checkout).
