test codewhisperer coverage changes (aws#5334)

* fix: Codewhisperer underreporting codecoverage

Problem:
- Codewhisperer was underreporting code coverage because c8 couldn't "see" the code in core

Solution:
- Use --allowExternal which allows c8 to report codecoverage on code outside of the cwd

Other notes:
- As far as I can tell/understand include isn't really necessary since we're using the "all" flag which considers all files in the cwd, --allowExternal which allows for src files to be outside of the amazonq directory (so it can see and report on the amazonq/codewhisperer test files), and exclude which specifically excludes certain files from the report
