chore(saucelabs): update sauce access key for lower rights (#2187)

Previous sauce access key had an admin right, even if no security issues were available it was still not so good (allowed people to create more users).

Now this key is the one from a subaccount of `instantsearchjs` user on saucelabs, with regular user rights.
