alias gd with dandavison/delta

Note dandavison/delta#152
is causing a (small) change in that WS intendation is
no longer ignored, but it's still possible to use git diff -w.

PS: I also considered https://github.com/so-fancy/diff-so-fancy
but opted for delta after reading https://dandavison.github.io/delta/features.html
and seeing https://dandavison.github.io/delta/comparisons-with-other-tools.html
