Clarify installation, fix typos, add warnings

[riverar]

Fixed:

• Clarified installation language in Server Core section
• Added warnings in each section about 60 day cert expiration
• Fixed up all references to Honolulu to be explicit -- Project Honolulu
• Removed warning about PowerShell auto-complete, completely irrelevant to Project Honolulu
• Removed reference to Chrome, expanded IE to Internet Explorer in spots

Overall language is still iffy, but at least it's usable now.

Hi Rafael,

Sorry it's taken a while to get back to you on this. We needed to investigate some of your revisions.

We are able to merge this PR with the exception of this:

Removed warning about PowerShell auto-complete, completely irrelevant to Project Honolulu

We have had multiple customers report this issue with 100% repro.

Please replace that warning in your PR, resubmit, and then we should be good to go.

Thanks,
Corey

Hey @coreyp-at-msft, I'm sure they reproduced it but you can also run into trouble typing gibberish, trying to left-click with the right mouse button, and trying to type with the keyboard flipped on your desk.

Having warnings on a product page for general computing issues seems out of scope.

@riverar I don't think that typing the first few letter of a file name and pressing [tab] to autocomplete is equivalent to

typing gibberish, trying to left-click with the right mouse button, and trying to type with the keyboard flipped on your desk

In most cases, the .\ added by PowerShell autocomplete does not effect the outcome of the command, so I also disagree that this is a "general computing issue"

[riverar]

I don't agree but will defer to Microsoft team guidance here. 👍

• Re-added warning (and moved the bottom one up a bit to prevent two warnings in a row)
• Threw in a few back ticks and fixed a typo

I'm merging now - will pull into private repo and publish this afternoon.

Hey @lizap, how are "contributors" identified on the docs site? I don't appear there. If this is purely for employees, what's the point of showing them?
