fix(ci): prevent parallel git diff when detecting new issues in monorepo

[matejchalk]

3 different monorepos have encountered the same bug, recently. It happens towards the end of the run, after bulk compare has completed succesfully.

 NX   Successfully ran target code-pushup for 8 projects




file:///home/runner/work/_actions/code-pushup/github-action/v0/node_modules/simple-git/dist/esm/index.js:4462
        return { error: new GitError(void 0, error.toString("utf-8")) };
^
Error: fatal: Unable to create '/home/runner/work/radar-kit-fu/radar-kit-fu/.git/shallow.lock': File exists.

Another git process seems to be running in this repository, e.g.
an editor opened by 'git commit'. Please make sure all processes
are terminated then try again. If it still fails, a git process
may have crashed in this repository earlier:
remove the file manually to continue.

After inspecting the source code, I believe the cause was findNewIssues being run in parallel, because it performs Git operations - git fetch origin main --depth=1 followed by git diff FETCH_HEAD HEAD ... - which fit the error message.

Refactored to ensure these operations are run sequentially.
