Use micromatch instead of minimatch (#46)

* Use micromatch instead of minimatch

micromatch claims to support full Bash 4.3 spec and it actually passes all the tests. 
For example this fixes processing of '!(**/*.tsx|**/*.less)' pattern - needed by #45

 ## Notes:
-- Paths expressions are evaluated using [minimatch](https://github.com/isaacs/minimatch) library.
+- Paths expressions are evaluated using [micromatch](https://github.com/micromatch/micromatch) library.
   Documentation for path expression format can be found on project github page.
-- Minimatch [dot](https://www.npmjs.com/package/minimatch#dot) option is set to true.
+- Micromatch [dot](https://github.com/micromatch/micromatch#options) option is set to true.
   Globbing will match also paths where file or folder name starts with a dot.
 - It's recommended to quote your path expressions with `'` or `"`. Otherwise you will get an error if it starts with `*`.
 - Local execution with [act](https://github.com/nektos/act) works only with alternative runner image. Default runner doesn't have `git` binary.
   - Use: `act -P ubuntu-latest=nektos/act-environments-ubuntu:18.04`
