Mark interactive graph widget as accessible! (#2288)

## Summary:
Now that the Interactive Graph updates phase 1 is coming to a close,
we can mark the Interactive Graph widget as accessible.

And since the new mobile version is released, it also means that
Interactive Graph is no longer reserved for assessments only.

Issue: https://khanacademy.atlassian.net/browse/LEMS-2522

## Test plan:
- Bump the Perseus version in webapp using this PR version
- Check in local devserver that the interactive graph
  "Requires screen or mouse?" checkbox is no longer
  auto-checked and disabled.
