Support additional `describe` aliases

[blimmer]

Would you consider support for identifying describe aliases (like context)? I've got a client that sets global.context = describe so they can write tests like:

describe('some method', () => {
  context('when something is true', () => {
     beforeEach(() => {
       // make 'something' true
     });
     it('does things', () => {
       // test
     });
  });
});

This used to be a jest feature, and it seems like some folks are still using this global trick like they are: jestjs/jest#2468.

Sadly, because they use context, it breaks a vs-code plugin I use (https://github.com/firsttris/vscode-jest-runner) because only describe blocks are identified by this package.

looks like "context" was removed explicitly (jestjs/jest#2468). Supporting it here is not hard, but it might be in users' best interest to move on from context and adopt the officially supported standard...

Yep, I saw that they removed context a while back. I think context is a useful semantic alias to use and other frameworks (like Mocha, RSpec, etc.) support its usage.

Support in this plugin would be super-nice because it would allow configuring the behavior that best suits their team's testing best practices. I would expect it wouldn't be a default behavior, so most users wouldn't notice the change in this repo. However, I also understand if you prefer to keep this project focused on the officially-supported behaviors of `jest.
