Show only agreement related info during install

This PR cleans up the install flow to make it easier for a user to see the agreements of the package. It does this by changing the install flow to not show fields that are unrelated to package agreements such as

• Moniker
• Description
• PackageUrl
• ReleaseNotes
• ReleaseNotesUrl
• InstallationNotes
• Documentations
• Tags

If we want to emphasize agreements in the prompts, I think we should modify the ShowPackageAgreements method to show agreements + basic necessary info only, and not reusing the ShowPackageInfo directly. We may add more things to "winget show" for package info in the future, and if we don't remember to treat them separately for ShowAgreementsOnly, it will be shown in ShowPackageAgreements.

We just did a servicing release yesterday, so it will be in next servicing release if we decide to do one. Sorry..

I don't have any concerns with the different output formatting for the Agreements flow.
No fields were removed from the "msstore" source, and the ones pruned from the community repository are fine as they are still visible via winget show and from the "source of truth" at GitHub.
