Overview

This PR introduces a couple small changes so that the CLI and specifically ditto scan are more productionized:

1. Show a formatted error message when a scan is run on a free or trial plan and exceeds the limit of extracted candidate strings (1000)
2. Make the path param for the scan optional. Omitting the path defaults to the cwd. This allows a user to run npx @dittowords/cli scan which will install, prompt the user for an API token, and run the scan from the current directory, all in one command.

Test Plan

Testing successfully completed in via:

• Ensure unit tests pass
• Test the CLI works on a repo without passing the path argument, e.g. yarn scan from the cli repo will run the scan on the CLI repo.
• Run the ditto scan on a repo that trips the max candidates error and ensure the error displays properly with a link to upgrade plan
