Some Readme content edits

[mjbear]

Overall some minor items in the Readme content.

• Fix typo(s)
• Change quoted area to an Alert (a.k.a. admonition)
• Replace a broken netdevops.me hyperlink with an archive.org copy of that page
• Move the Connection Mode list into a table
• Various wording and sentence changes (admittedly my take and can be adjusted)
• Markdown linting-esque changes
  • (full MD linting and GH Actions for another PR!)
  • Surround MD headers with white space
  • Break long MD lines into shorter lines

I'm open to feedback and any tweaks/changes.

Thank you @hellt
I'm going to give the documentation another read or two. I'll mark it as "Ready" when I have it ready for merging.
Thank you!

@hellt
Admittedly my take on some of the sentences and wording. Hopefully I didn't distort the intended information and message.

Just like your earlier suggestions, I'm open to them. 😀
