insert-license hook ignores top-level files selected by `types` or `types_or`

https://github.com/Lucas-C/pre-commit-hooks/blob/master/.pre-commit-hooks.yaml#L33 has line files: '.*/.*'. This overrides defaults and ignores top level files from project (top-level files don't have / in path when pre-commit is run).

Example when insert-license hook omits useful files (example uses language: fail just to print filenames passed by pre-commit):

repos:
  - repo: https://github.com/Lucas-C/pre-commit-hooks
    rev: v1.3.0
    hooks:
      - id: insert-license
        types: [makefile]
        language: fail
  - repo: https://github.com/pre-commit/pre-commit-hooks
    rev: v4.2.0
    hooks:
      - id: end-of-file-fixer
        types: [makefile]
        language: fail

The output for running pre-commit:

$ pre-commit run --all
Insert license in comments...............................................Failed
- hook id: insert-license
- exit code: 1

insert_license

doc/Makefile
src/Makefile

fix end of files.........................................................Failed
- hook id: end-of-file-fixer
- exit code: 1

end-of-file-fixer

Makefile
doc/Makefile
src/Makefile

Note fix end of files hook from https://github.com/pre-commit/pre-commit-hooks prints top-level Makefile while insert-license doesn't.

Adding files: '' in user's .pre-commit-config.yaml restores the default behaviour and top-level files are passed correctly to entry command.
IMHO, it's better to remove all files: ... altogether from .pre-commit-hooks.yaml.
