feat: create_next_version -> create_next_component_version (#215)

Since the authoring apps now have their APIs aggregated into the public
openedx_learning.api.authoring module, "create_next_version" will be
ambiguous as soon as we create other versioned things like Units.

I'm including an alias to give more flexibility for switching
edx-platform over.

While this is largely refactoring work, it also effectively adds a new
function to the public API, which is why this commit is marked as "feat".
