Creation of a new spk fails to trigger build

[th0ma7]

Is this a new Bug?

• I checked that the bug hasn't been reported before

Package Name

synocli-wheels

What happened?

Relates to #6282 where new package synocli-wheels does not get trigered upon build.

Suspecting an oversight with recent changes to github-action.

This already popped up latelty. I guess it could be an issue when creating the dependency list with bash variables.
variables are limitted to 1024 chars so dependencies could be lost...
should be addressed in #6255.
