fix(readme): update compatibility table and remove API column

[pichlermarc]

Which problem is this PR solving?

The table needed to be updated, and API version requirements seemed to be more restrictive than they actually were. This PR removes the API column and instead adds notes to the SDK versions that require newer API versions.

Fixes #4094
