This looks good, but we should also remove all inline references to Ubuntu since it's implied now. There were a couple other references that I couldn't reply to, on lines 154 and 178 in the original file, so you'll want to get those too, probably just want to search the file and make sure the only reference to Ubuntu is at the top 😄

I also think we should remove Ubuntu 18.04 and add 24.04 to the list now that it's been tested.
