docs(): Fix changelog link in whats-new-in-v2-1

I noticed a typo when I was reviewing the docs ...

fix(build): minor fix for build script to make latest copy for rpm when version is pre release version

fix(panel): fix for firefox and placing cursor in text inputs when in panel fullscreen edit mode, fixes #2957

The quotes turn the value into a title attribute rather than href attribute,
thus on http://docs.grafana.org/guides/whats-new-in-v2-1/ this link was

which when clicked goes back to itself (not to GitHub).
