feat(aio): use shorter URLs for previews

Browse Source 
Use the 7 first characters of the 40-chars long SHAs for shorter/cleaner URLs.
The collision probability is extremely low (since all SHAs are further
"namespaced" under the corresponding PR). In case of a collision, the second PR
will not be deployed, in order to avoid overwriting the original build.

(This is a design decision to keep the implementation simple. It can be changed
later if necessary.)
