Changes regarding the initialization path for JS vs Native for RN

Checklist before you pull:

• Double-check that any changes fit the Embrace Docs Style Guide.
• Please ensure that there is no customer-identifying information in text or images.
• If you changed any doc file names, add a redirect from old to new URL so that we don't end up with broken links. You can do this by adding a set of to/from values in docusaurus.config.js under @docusaurus/plugin-client-redirects.
• If you link to a header within a page in the docs, make sure that header has an explicit tag in case it changes in the future. E.g., the H3 header ### Hello World {#my-explicit-id} has an explicit tag my-explicit-id.

given the new emphasis we should maybe rethink even having those particular options in sdkConfig.ios since they'll be of limited utility, can be addressed separately from this PR though
