Align on config name for use import access level (#35)

Motivation:

When the plugin was done we went through a few iterations of the shape
of config and settled on `accessLevelOnImports` vs.
`useAccessLevelOnImports` but that change wasn't made.

Modifications:

- Update config name.

Result:

API is what we planned it to be.
