Early February 2022 in Darker: Compatibility Fixes and GitHub Action Improvements

[akaihola]

This month, we addressed several issues to improve Darker's compatibility and functionality. A significant change in Black v22.1.0 led to incompatibility with Darker (#264). The root cause was traced to Black's find_project_root() function now returning a different type than expected. This affected both local installations and our GitHub Action, causing errors when locating configuration files. We're working on a fix in #270 to resolve this issue.

We also made progress on enhancing our GitHub Action. An issue was reported regarding the action checking against the HEAD commit, resulting in no diff (#260). We're exploring solutions to improve diff comparison for push and pull request events. Additionally, we're looking into adding syntax highlighting to the GitHub Action output to improve readability (#263). On the integration front, we're considering adding information about pytest-darker to our README (#265), enhancing our documentation for users.

Lastly, we addressed a minor issue with the --stdout flag adding an extra newline to the output (#250). We're reviewing this behavior to ensure consistent formatting across different usage scenarios.
