Otto Richter d97e36f6d7 Playwright testing for commit diffs
includes:

- easier repo declaration for playwright tests by @Gusted
- full backend build for pushing Git repos by @Gusted
- playwright testing (which fails with the current diff algorithm, but
  passes with the new)
- disable eslint rule for conditional expect, because it defeats the
  purpose (working around it would result in much more complex test code
  in our cases)
