(Fix): Support latest trivy version

[TylerJang27]

Trivy yanked almost all their releases yesterday except for v0.69.2. Change KGV from 0.67.2 to 0.69.2.

This latest version fails frequently for parallel runs when fetching rulesets and overwriting them in the shared_cachedir. This can be resolved in 3 ways:

1. A prepare_run command that fetches the rulesets. Unfortunately we don't support template resolution atm for prepare_run
2. Skip fetching rulesets on every invocation (this would be a fairly large breaking change)
3. Limit to 1 concurrent runs (too slow for most cases)
4. Use a tmpdir for the cachedir (slower and uses tmp space but the easiest path forward)

I intend to do a patch release after this.
