RFR: mlbridge: use nicer link for webrev commits

[Erik Helin]

Hi all,

please review this patch that formats the link to the commit after a webrev version a bit nicer. After my change in f16663b766fa02ced204bb1ca8d334a4ca776092 we are showing the full link, which is a bit verbose. This patch restores the old behavior where we just show an abbreviated hash.

Thanks,
Erik
