Remove scan dependencies git hook (#132)

## Description

There is not much benefit in running a potentially outdated CVE check
locally, especially considering that the GitHub Action always performs a
check against the latest version.

- Fixes #128 

## Context

Grype [updates its
database](https://github.com/anchore/grype#data-staleness) at the first
run or every 5 days. The size is approximately 1GB. It may take minutes
for the scan dependencies git hook to complete. This is not a good user
experience.
