feat(component): Create new component for feature information in quick start guides

[inventarSarah]

DESCRIBE YOUR PR

Background:
In our quick start guides, we have two Expandables that explain Sentry features:

• "Do you want to learn more about these features?"
• "Need help locating the captured errors in your Sentry project?"

I created these as PlatformIncludes, which led to:

• inconsistency because listed features didn't always match the actual onboarding options
• multiple files containing the same content
• updating feature descriptions or adding a new feature required editing multiple files

Changes:
Created a new component that

• centralizes feature descriptions in one file
• supports "learn more" and "find in Sentry" content types
• works across languages and platforms (it is not JS-specific)
• makes it easier to add new features or update descriptions/links etc

I updated all the quick start guides to use the new include & component and removed the old PlatformInclude files.

closes: #16320

LEGAL BOILERPLATE

Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. and is gonna need some rights from me in order to utilize my contributions in this here PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.
