melangeignore does not result in files ignored

[jdolitsky]

Maybe a problem here, or in melange, or most likely in the upstream GitHub actions. Perhaps related to #2 as the workspace does not appear as expected.

In the build we do

echo ".github/" >> .melangeignore

But in the melange run, we see
