Do not override an existing wheel the same name as a new wheel

[pzhou-splunk]

Notes

• When a git repo is specified as a dependency, pip will always clone the repo and build the wheel from scratch, where metadata in the wheel will be updated on each build
• Since I don't think there's a way to get pip to use an existing wheel in such cases (specifying a git repo implies that we're building from source), we can just let the wheel get re-built but discard it if there's already a wheel with the same name in the wheels/ folder

Testing

• pre-commit try-repo ~/git/dev-cicd-tools package-app-dependencies
