Full example for flux deployment

[nebulans]

Description Current example for flux does not give a specification for referenced helm repository. This makes deploying truecharts charts with flux harder than it should be.

Easy for users to get this wrong with confusion between OCI repositories & Helm repositories with an OCI URL.

Looks fine to me, just leaving this for @Ornias1993 to confirm when he has the time.

@bitpushr WTF, why did you merge then when I explicitly vetoed it?!
