As we add several new commands like inspect, linting, formatting, data provenance, the CLI is getting crowded.

There are several commands for managing pipeline projects:

• clone
• drop
• list
• pull
• view

I think all of these commands could be combined into a single command e.g. projects or repos:

nextflow projects list
nextflow projects pull <project>
nextflow projects view <project>
...

Similar to what we are doing in #5715

We can keep the existing commands as redirects and hide them in the CLI help, so it should be easy to transition.
