Add expected regex syntax to hints kitten docs

Browse Source 
The hints kitten's help documentation did not mention what syntax to use
for the regular expressions. I knew much of kitty was implemented in
python so I guessed correctly but not everyone might know this.

I also fixed some double-spaced sentences because most of them are
single-spaced.

The regular expression to use when :option:`kitty +kitten hints --type`=regex.
If you specify a group in the regular expression only the group
will be matched. This allow you to match text ignoring a prefix/suffix, as
needed. The default expression matches lines. To match text over
multiple lines you should prefix the regular expression with :code:`(?ms)`,
which turns on MULTILINE and DOTALL modes for the regex engine.
