CI: Fix the no such file or directory error with the working directory.

Fix the error with the working directory in the result job in some GitHub
Actions YAML files. I hit this error on my forked repository below.

```
Error: An error occurred trying to start process '/bin/bash' with working directory '/Users/runner/work/ruby/ruby/build'. No such file or directory
