Ed Page 36bc641648 fix(help): Remove extraneous text from built-ins
This is an intermediate solution for #4408.  As there were no agreeed
upon goals, I went with what I felt read well and that I saw commonly
used on non-clap commands.

- "information" isn't really a necessary word.
- I originally favored `Print this help` but realied that doesn't read
  correctly in completions.
- Besides being shorter, the reason for the flipped short/long hint is
  it gives people the context they need for scanning, emphasizing
  "summary" and "more".

Fixes #4409
