assert.deepInclude() is not a function - update Chai to >=4.1.2

[cuteporing]

Current behavior:

Chai Assertion Library (http://www.chaijs.com/api/assert/) was referenced from Cypress.io Assertion docs (https://docs.cypress.io/guides/references/assertions.html#BDD-Assertions)

so I was under the impression that these API's actually works on Cypress.io. Some does like

assert.include()
assert.notIinclude()
assert.deepEqual()
assert.notDeepEqual()

but others don't like assert.deepInclude()

as shown on the screenshot below:

Desired behavior:

It would've been nice if this also works on Cypress. Otherwise the Chai Assertion Library link should not be part of the document for Cypress since it's going to be confusing.

Versions

Cypress: 2.1.0

I believe deepInclude was adding to Chai in version 4.1.2: chaijs/chai@7d1dd30

Cypress is using an older version of Chai and would need to update it for this to work.

This will work after updating Chai, which has a PR open for our 4.0 release.
