WIP: rules: Add "xdg-open" symlink to the alternative steam-runtime-urlopen
rules: Add "xdg-open" symlink to the alternative steam-runtime-urlopen
"steam-runtime-urlopen" is an alternative "xdg-open" executable that provides better Steam's URL handling.
This depends on steam-runtime-tools!283 (merged) and includes !97 (merged) (is not required, but because has already been approved this avoids a possible merge conflict)
After the merge it needs to be cherry-picked for Soldier and Sniper too.
