Remove the New Photo Post app shortcut

[kean]

Part of #21190

We needed to either update this feature to support the new native photo picker or remove it. Because nobody was using it (<30 uses in the last 12 months), we decided to remove. Makes for a clearer shortcuts menu. Discussion: p1692303663191839-slack-C04SFL0RP51.

This is how this feature used to work:

Simulator.Screen.Recording.-.iPad.Air.5th.generation.-.2023-08-17.at.16.13.27.mp4

To test:

• Verify that the remaining shortcuts still work

Regression Notes

1. Potential unintended areas of impact: App Shortcuts (or, technically, "Quick Actions")
2. What I did to test those areas of impact (or what existing automated tests I relied on): Manual
3. What automated tests I added (or what prevented me from doing so): n/a

PR submission checklist:

• I have completed the Regression Notes.
• I have considered adding unit tests for my changes.
• I have considered adding accessibility improvements for my changes.
• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

UI Changes testing checklist:

• Portrait and landscape orientations.
• Light and dark modes.
• Fonts: Larger, smaller and bold text.
• High contrast.
• VoiceOver.
• Languages with large words or with letters/accents not frequently used in English.
• Right-to-left languages. (Even if translation isn’t complete, formatting should still respect the right-to-left layout)
• iPhone and iPad.
• Multi-tasking: Split view and Slide over. (iPad)

I'm going to bump this to the next release because we'll be code freezing 23.1 today and this hasn't been approved yet.

If this cannot wait two weeks and it's important that it makes it into this release, let me know and we'll organize a new beta once ready.
