WIP: Remove 'Timed out retying' for timeout errs

addresses #887

I really feel like this doesn't actually help with much. After our internal discussion we decided that it made sense to remove this one line, but that we should further explain the retrying effect underneath the error.

[brian-mann]

Maybe we could add something like: It retried for XXXXms and eventually gave up.

I would definitely be up for adding this text at the end of the error as opposed to reverting back to how it is now. I can revisit adding this to the bottom, but I'd have to investigate if this xxxxms data is readily available to add to the error.

What about adding the 'for xxxxms' at the end of the error, I'd have to look at each situation to see if this verbiage works. Like:

CypressError: Expected to find element: '.text-input', but never found it. queried from element: #my-form for 4000ms

[brian-mann]

Another thing we talked about was not displaying CypressError. That will take a bit more logic, but is definitely do-able.

[jennifer-shehane]

Yes, we should probably split that into a separate issue. This issue is also related to the 'CypressError' wording: #825

Closing. Was not approved. Hopefully these doc improvements help cypress-io/cypress-documentation#1314
