Remove quotation marks

[Vicropht]

CNAME file doesn't work if there are quotation marks in the domain, I had trouble with my own due to copying and pasting this command as it is. Removing the quotations made it work again.

Thanks, @Vicropht. The echo command should not output the quotes (e.g. echo 'foo' > bar should result in a bar file containing the string foo). Curious where this might not be true.

The reason for the quotes is to avoid interpreting special syntax in the string (see https://mywiki.wooledge.org/Quotes). But its ok by me to remove it in the docs here.
