feat(plugins/scaffolder-backend): add new fs:readdir action

[secustor]

Hey, I just made a Pull Request!

Adds a new action ( fs:readdir ) which allows to retrieve the current content of the workspace.

In my current use case I need this to create on PR per folder in the workspace, though there are a lot of other use cases e.g. output texts

Looks good to me, although the distinction between files and folders may be a little bit arbitrary - by which I mean, could have been a flat list with type fields just as well. So it's made this way to solve a certain use case of course. Could also have had an input argument that selects what types of thing you are looking for, I guess; matter of taste. WDYT @benjdlambert ?

My thought has been, to allow easier access for users for common cases as filtering can be a pain with Nunjucks.

That being said I'm open to create a third generic elements or dirent output, which contains the other two outputs combined.
