Remove domain for testing setup

[asmacdo]

Builds on #496 to avoid merge conflicts. If you prefer, we could just merge this one and close the other.

Thanks @vinicusdc for the suggestion nebari-dev/nebari#2555 (comment)

What does this implement/fix?

The local deployment docs include setting domain, which doesn't work out of the box without setting up DNS, which I've also added a link to.

Put a x in the boxes that apply

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds a feature)
• Breaking change (fix or feature that would cause existing features not to work as expected)
• Documentation Update
• Code style update (formatting, renaming)
• Refactoring (no functional changes, no API changes)
• Build related changes
• Other (please describe):

Access-centered content checklist

Text styling

• The content is written with plain language (where relevant).
• If there are headers, they use the proper header tags (with only one level-one header: H1 or # in markdown).
• All links describe where they link to (for example, check the Nebari website).
• This content adheres to the Nebari style guides.

Any other comments?

Local deployment with kind seems like the entrypoint for prospective users. Making this doc work smoothly out-of-the-box should be helpful I hope :)

@viniciusdc thanks for the review, it feels less clunky now. Let me know if theres anything else :)

Hi @asmacdo sorry for the delay on this, got a busy ending of August. I plan on taking another look at this during this week. I noticed that there seems to be a conflict with some files above, if you had the time can you fix these? Otherwise, if you don't mind I can amend those as well.

I clumsily combined GH suggestions with local pushes, sorry for the awkwardness, I think its correct now.
