Failing deployment of GH pages

[akoreman]

Issue

After merging in #5269 we have an .astro file in our repo which is getting picked up by the workflow we have to publish the Ace websites, this is causing the action to fail.

Issue seems to be that the GH action we use for this uses Jekyll which automatically picks up .astro files, I tried to add a file to tell Jekyll to ignore this fail but this didn't help.

Not sure whether this is because the ignore file is not being picked up or because there is something wrong with the content of the ignore file.
