help.fish: Fix the sed expression to find anchors with id or name

Browse Source 
Previously the expression only searched for anchors with a name
attribute, but doxygen 1.7.1 is producing anchors with the id attribute
instead. The sed expression allows both cases for compatibility.

I also used single quotes for the sed expression to avoid escaping
double quotes.
