Print hash with --version when installed as development

[stxue1]

It got annoying trying to figure out whether my installed Toil on the cluster was up to date with my commits, so this makes development builds print the hash.

Changelog Entry

To be copied to the draft changelog by merger:

• --version with development builds will now also output the commit hash
