feat(directives): allow ignore rules for copy

[hiddeco]

This adds the option to configure ignore rules for the copy directive, i.e.:

steps:
- uses: copy
  config:
    inPath: ./src
    outPath: ./dst
    ignore: |
      # Ignore all *.log files
      *.log
      # Except for the ones in ./src/foo
      !foo/*.log

By default, the .git/ directory is ignored. However, this can be overwritten using:

steps:
- uses: copy
  config:
    ignore: |
      # Overwrite default exclude with explicit include
      !.git/

By default, the .git/ directory is ignored.

.git is a directory, of course, for a typical clone, but for a working tree of a bare repo, .git is a file.

By my reading of the code, the pattern you are using is .git (and not .git/), so I think our bases are covered, but I just wanted to double-check with you.

[krancour]

I see you amended the tests to assert that .git dir and .git file are both covered by default.
