Change in JSON output of screenshots.debian.net

[Raphael Hertzog <hertzog@debian.org>]

Hello Christoph & Paul,

I have been getting failures from tracker.debian.org since July 22 about
UpdatePackageScreenshotsTask now failing with this error:

TypeError
list indices must be integers or slices, not str

I believe that https://screenshots.debian.net/json/packages used to be a
dictionary with a single "packages" key (which was a list of all the
packages).

Now it looks like the top-level dictionary is gone and we directly have
the list of packages. Is that on purpose and will it stay that way?

I'd like to know if I have to fix tracker.debian.org, or if it's a mistake
that you plan to revert in some way.

Thank you!

PS: https://salsa.debian.org/debian/debshots still defaults to the master
branch instead of main... I was first surprised to not find any recent
change explaining this change of behaviour (until I discovered the main
branch).

The only revelant commit seems to be
https://salsa.debian.org/debian/debshots/-/commit/daa6d7c4b474c52e41e9601a50d87a5dd1d681ec
but I fail to see how it can have this impact.
