Fix formatting in documentation

Removed trailing whitespaces and extra newlines. Added some missing
punctuation. Replaced unicode characters that aren't commonly used
with the more common character.

The replaced unicode characters are
- ’ (U+2019) to ' (U+0027)
- “ (U+201C) to " (U+0022)
- ” (U+201D) to " (U+0022)

 `WARN asset size limit: The following asset(s) exceed the recommended size limit (244 KiB).` - For the PWA to support Windows 10, a splash screen asset is required, and is quite large.
