`--commit-range` doesn't restrict the recommendations to changed files in that range

[jaron-l]

Issue

When I run the cli command to get a security scan for a given commit range, it includes recommendations across the entire package rather than just the specified commit range.

Steps to reproduce

1. Run aws-codeguru-cli --root-dir . --profile <profile> --mode security --commit-range HEAD^:HEAD
2. Observe the the file at code-guru/recommendations.json includes recommendations across your entire package.

Expected Result

Only include recommendations that are part of the diff within the commit range.

Notes

I tried removing the commit range and noticed that the output is identical which makes me think that the flag is ignored.

This seems related to #9 but I wasn't able to validate the output of the jobs mentioned in that query.
