Switch to 0.4.0 and eliminate Chart app versions. (#810)

Why are these changes needed?
This PR updates version tags in the release branch to 0.4.0.
Once this PR is committed to the release branch, final 0.4.0 artifacts will be built from the branch.

This PR should only be merged once we're ready to go through with the final release.

Removing app version
I've made a decision here to remove appVersions for the Helm charts.
appVersion is optional and I don't believe we need an extra version string floating around.
I'm open to keeping appVersion if anyone thinks it's needed.
