Editor Onboarding: "The Basics" help section - Topics List UI

[AmandaRiu]

Gutenberg PR: WordPress/gutenberg#33240

Description

This PR is the first in a series of PRs to add the Editor onboarding basic help section defined in this ticket: WordPress/gutenberg#30626 and covers the following:

• Adds the "Help" menu option to Gutenberg demo app on Android and iOS to make testing easier.
• Adds the main help topics bottom sheet. Clicking these items will just log "onPress" to the console at this point. The sub-page displaying the contents of each help topic will be in a separate PR.
• Added additional icons to the @wordpress/icons package where needed to match the designs.

PR submission checklist:

• I have considered adding unit tests where possible.
• I have considered if this change warrants user-facing release notes more info and have added them to RELEASE-NOTES.txt if necessary.
