feat(mac-crafter): retry code-signing attempts

This step sometimes fails with an error such as: "A timestamp was
expected but was not found.".  Any code-signing errors will result in
the notarisation step to fail.

Apparently this might be due to intermittent network issues.  Let's just
retry codesigning a couple of times in the case it fails ...
