[fish] Use $version instead of $FISH_VERSION (#1100)

Browse Source 
$FISH_VERSION is dropped in 2.7, but every version has $version

Comment from @faho in #1316:

Unfortunately, $FISH_VERSION was only ever a thing from fish 2.0 to fish 2.7.1.

All fish versions from the very beginning though used a variable called simply "$version" to store their version, so that is the one that should be used.
