Backend: Increase the 10 component per project limitation to 30
### Problem
Currently, our documentation mentioned that
> All components in the project are versioned together, with a maximum of 10 components per project.
This limitation would need to be increased prior to GA
### Proposal
Based on user feedback let's increase it to 30
