Is your feature request related to a problem? Please describe.

Current image version 1.5.0 of jnorwood/helm-docs in Makefile only supports amd64, which makes "make reviewable" not runnable on a linux VM on MacOS arm without other changes.

Describe the solution you'd like

Update the helm-chart image version to i.e. 1.7.0, so it's possible to run the "make reviewable" on macos arm.
