Remove "starter" plan checks from team invitation logic (#7513)

<!-- start pr-codex -->

## PR-Codex overview
This PR focuses on refining the invitation feature within the onboarding and settings sections of the application. It simplifies the conditions for inviting team members based on the billing plan.

### Detailed summary
- Removed `"Invite Team Members"` from the pricing options in `pricing.tsx`.
- Updated the conditional rendering for the custom CTA in `InviteTeamMembers.tsx` to check only for the `"free"` billing plan.
- Simplified the `inviteEnabled` condition in `InviteSection.tsx` to exclude the `"starter"` plan.
- Adjusted the conditional check for displaying the bottom section in `InviteSection.tsx` to only check for the `"free"` plan.

## Summary by CodeRabbit

* **New Features**
  * Updated team plan features by removing "Invite Team Members" from the "growth" plan feature list.

* **Bug Fixes**
  * Adjusted upgrade prompts and invite functionality so that upgrade options and invite restrictions now apply only to teams on the "free" plan, rather than both "free" and "starter" plans.
