Build process for release notes

[Baptiste Jammet <baptiste@mailoo.org>]

Hello -www team,

Receiving #904525 on -doc, I found that the cron script for building the 
release notes on the website has not been updated to use git on Salsa.
(7doc_manuals neither)

Attached is a partially tested patch to cron/parts/7release-notes
I used plain git, because the update could be more efficient. But maybe 
wget *.tar.gz is preferable?

I hope this can help.
