validate-bundle has no default value for --report-dir

🐛 Describe the bug

When you run validate-bundle without including --report-dir, the default value for the internal REPORT_DIR is empty. This leads to the default value for the internal REPORT_FILE to become /validate_summary.log and the default value of the internal RUN_DIR to become /. This obviously creates a permissions issue when trying to create validate_all_files.txt. This results in validate-bundle reporting that there are no products to validate (because validate_all_files.txt doesn't exist), exiting the program.

As a side note, the usage message says that --dir-path is the long form of -d but in the actual code it's --report-dir.

🕵️ Expected behavior

I expected --report-dir to have a default value set if it's not included in the validate-bundle call. It's listed as an optional parameter but to have validate-bundle function correctly, it's currently behaving as a required parameter.

📜 To Reproduce

1. Execute validate-bundle --target-bundle /path/to/bundle.xml
