Support for wildcard pattern matching

[LMaxence]

Description

It would be nice to have to ability to declare the path of a folder, and have the labeler automatically match folders below that path, and automatically create tags like so:

{parent folder}:{matched folder}

For instance, with this setup:

-- packages
----- package A
----- package B
-- services
---- service A
---- service B

and the following auto_labels.json

{
  "files": {
    "packages/*": "packages",
    "services/*": "services"
  }
}

I would like to create the tags packages/packageA whenever packageA is modified (and only when it is modified). Same for packageB, serviceA and serviceB.

Perhaps an easy implementation could involve to simply pre-process the auto labels json config file, and extend the wildcards into classic label matching rules for every folder that would match the wildcard.
