chore: install snyk before generating report

[crenshaw-dev]

First timed run of the snyk report was a raging success.

./hack/snyk-report.sh: line 67: snyk: command not found

The flag change is in response to this:

npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead.
