Docs consistency issues

Anyone can contribute to the GitLab docs. If you are a community contributor or GitLab team member, you're welcome to fix any of the following issues. Search the GitLab repo and:

• Remove "note that"
• Remove "respectively"
• Remove "please"
• Change "normally" to a more appropriate word.
• Ensure there is one space between the number and GB, MB, etc.
• Change "e.g." to "for example"
• Change "i.e." to "that is"
• Change "Ex:" to "for example"
• Change "above" and "below" to the "previous" and "following"
• Get rid of "let's" as in "let's say" unless we are in a tutorial
• Fix usage of "toggle"
• Search for page. Page names should be bold.

Note: You do not need to update any files in the doc/development directory.
