Upgrade cli dependencies

[singingwolfboy]

The cli/package.json file declares a lot of dependencies, and they are all pinned to exact versions. This means they fall out of date quickly, and any other project that depends on cypress must pull in these old versions of these dependencies for cypress.

This pull request updates all dependencies in cli/package.json. This is probably more extreme than what we want, but it's a good first pass to see how much we need to change the code to accommodate these dependency updates. I'm happy to break this up into smaller pull requests, if asked.

PR Review Checklist

If any of the following requirements can't be met, leave a comment in the review selecting 'Request changes', otherwise 'Approve'.

User Experience

• The feature/bugfix is self-documenting from within the product.
• The change provides the end user with a way to fix their problem (no dead ends).

Functionality

• The code works and performs its intended function with the correct logic.
• Performance has been factored in (for example, the code cleans up after itself to not cause memory leaks).
• The code guards against edge cases and invalid input and has tests to cover it.

Maintainability

• The code is readable (too many nested 'if's are a bad sign).
• Names used for variables, methods, etc, clearly describe their function.
• The code is easy to understood and there are relevant comments explaining.
• New algorithms are documented in the code with link(s) to external docs (flowcharts, w3c, chrome, firefox).
• There are comments containing link(s) to the addressed issue (in tests and code).

Quality

• The change does not reimplement code.
• There's not a module from the ecosystem that should be used instead.
• There is no redundant or duplicate code.
• There are no irrelevant comments left in the code.
• Tests are testing the code’s intended functionality in the best way possible.

Internal

• The original issue has been tagged with a release in ZenHub.

@types/blob-util is deprecated, since blob-util now bundles its own type definitions.

@singingwolfboy Closing in favor of #4226 which does exactly this.

A large amount of the upgrades are breaking changes - dropping Node 4 and 6, which is why we have it slated for the breaking change release of Cypress.

We use renovatebot to update dependencies one by one for better tracking generally, so do not generally consider PRs for dep updates outside of the flow. See our Contributing guide for more detail.

I will open a new issue concerning @types/blob-util dep. Thanks!
