[enh] theme/simple: package.json revision

Set minor versioning for most of the packages that iterate fast or we know won't
cause problems, and fixed versioning for the rest.

Packages going into bundles should be placed in "dependencies".

The inspection of prod bundles is necessary. Although it does not make a lot of
sense right now, it will be useful in later PR and will give us a reference to
start with.
