[DOCS] Fix formatting for lists in .rst

If there is not a newline before and after the list, the list
may not be formatted correctly.

A newline was added before and after lists in .rst files.

Additionally, some lines beginning with "- " (which would result
in false positives when checking) were modified so that list checking
can be performed more easily in the future.

Lists can be checked for example by using the following regular
expressions:

find typo3/sysext/*/Documentation -name "*.rst" | while read i;do
  grep -B1 -H -E "^(\-|\*)\s" "$i" | grep "\.rst-" \
    | grep -v -E "\.rst-($|\-|\*|\s)"
  grep -A1 -H -E "^(\-|\*)\s" "$i" | grep "\.rst-" \
    | grep -v -E "\.rst-($|\-|\*|\s)"
done
