Identify the source of the unused linting warning for setOverridesFlag

[komish]

In cmd/verify.go https://github.com/redhat-certification/chart-verifier/blob/main/cmd/verify.go#L47, the setOverridesFlag triggers golangci-lint because it's unused.

We should verify that it's unused, try to find places where its use is intended but disconnected, and decide to either wire it in or remove it. Worth checking the commit where it was introduced, and any commits thereafter to see how it has been manipulated.

after some investigation it looks like this is the commit which removed the references to the "setOverridesFlag"
Seems as though it pretty much just replaces "setOverridesFlag" with "verifyOpts.values" and missed removing the initial reference
