feat(apple): Add docs for screenshot masking options

[philprime]

DESCRIBE YOUR PR

Adds documentation about configuring masking of screenshots. Based on the already existing session replay masking documentation. As the two options sets are different (options.sessionReplay.* vs options.screenshot.*) we should duplicate the documentation for now in case of drift.

We need to revisit this issue with https://github.com/getsentry/sentry-cocoa/issues/6060

BLOCKED BY https://github.com/getsentry/sentry-cocoa/pull/6953

[philprime]

As the implementation of a screenshot specific public API is taking longer than expected with https://github.com/getsentry/sentry-cocoa/pull/6953 I'll merge this PR now as-is and iterate the documentation when the new public API is available.
