The REST API returned 4xx on unknown object but valid JSON body. As
written originally, valid JSON was assumed (result queried on null).
So revert back the original curl calls where acquiring JSON.
import improvements from GPUJPEG - summary:
- LABEL - replace ' ' with %20 (will get to URL)
- use while instead of for..seq
- cat json file directly (avoid interpretting \n and \r that XSI-compilant
echo, as in dash, does)
- cat really the $json file, don't print its name
- wrap long lines + early return in while-loop
The rewrite of `for n in \`seq` may be perhaps a bit controversal
(with while is less readable) but technically POSIX doesn't specify the
seq comand.
- upload assets with script [nightly]
- remove unneeded Windows runner components (Android, dotnet) to free up
space (namely for Qt)
- no timeout for pacman (sometimes failed)
