FF Integration docs: Investigate need for react-specific setup/verify code

[aliu39]

Description

From slack:

Look into whether we need platform-specific code snippets, mostly for react. For all other browser JS platforms we expect users to use launchdarkly-js-client-sdk and @openfeature/web-sdk, so the code can be shared for those.

Can use <PlatformContent> for this.
Follow-up after the big open beta docs PR is merged

I'll move this issue to sentry-docs!
