Fix publishing of docs.o.o/infra/index

.root-marker. Copy over the whole directory, it contains only these two
files.
Without the root-marker, the file will get deleted later again.
remove-prefix: 'docs-site/output/'

site: 'afs-docs'
- source: 'docs-site/output/index.html'
+ source: 'docs-site/output/**'
target: 'infra/'
remove-prefix: 'docs-site/output/'
