improve brew info

* Show pinned and keg-only as attributes, where pinned
  version is shown as well.
* Use brackets instead of parentheses to distinguish formula
  attributes(e.g. keg-only) with spec attributes(e.g. bottled)
* Don't show blank line for formula without homepage.
* Don't show duplicated keg-only message which will be shown later
  in caveats.
* Underline urls.
* Remove unnecessary github_info return value check, which is always
  existed.

Closes Homebrew/homebrew#46037.
