feat: adds 'ancestor' matcher

[sverweij]

Description

• adds an ancestor matcher

Motivation and Context

It's probably possible to do this with regular expressions and group matching, but so far I haven't found a simple way to do that.

How Has This Been Tested?

• green ci
• additional automated integration tests
• additional automated unit tests
• self-run (added a no-ancestors rule to our own .dependency-cruiser.mjs)

Screenshots

You can now do things like this:

// in the `forbidden` section of a dependency-cruiser config:
{
  name: "no-ancestor",
  comment: "don't allow importing from folders above the current one",
  severity: "error",
  from: {},
  to: { "ancestor": true }
}

Which, when run as part of a validation, would yield errors on every dependency that goes folders up in stead of down:
