Clarify sharing projects documentation - group restrictiveness wording is confusing

Problem

The documentation for sharing projects contains confusing and potentially contradictory wording about group restrictiveness requirements.

Current Documentation Issue

The documentation states: "The group can't be more restrictive than the project."

However, the examples show the opposite logic - they demonstrate blocking groups that are LESS restrictive than the project.

Root Cause

Based on the commit history (e627f805), the original wording was: "The group you're inviting must be at least as restrictive as that of the project"

This suggests the actual requirement is: "The group can't be LESS restrictive than the project" (not "more restrictive" as currently stated).

Expected Behavior

The documentation should clearly state the correct requirement and ensure all examples align with this requirement.

Steps to Reproduce

1. Review the sharing projects documentation
2. Compare the stated rule with the provided examples
3. Notice the contradiction
