Implement In-App DevEx v2

[undavide]

Description

Implement UI/UX changes in the in-app distribution experiences. See this GDoc.

Affected documentation:

• Getting Started > Quickstart guide
• Distribute > Creating a private link
• Distribute > Creating a public listing

⚠️ Caveats

In the future, it might be worth revisiting Step 9: Create a publisher profile in public-dist.md. Given that I've used the Stage version with a privileged account from the Test Privileged Dev Org - stage group, I could not simulate the creation of a publisher (it was already there). Admittedly, even the existing version of the documentation is pretty thin in that regard; it shouldn't be a problem now, but when the changes are pushed to production, one can use a personal account to document the publisher creation better.
