Provide lint to integration package

[morningspace]

The CLI can be extended to support a lint command, that includes the needed rules for a qualified package before it can be published to the central registry, e.g.: the rules for package name, required metadata, access rule check, etc.

Once it's available, we can also add that to the workflow of this repo, so that if someone want to contribute by PR, the pipeline can be triggered to run lint against the user proposed package contents.
