bootstrap_barrio.post_update.php has blank prepended in its filename

I have removed the space before and created the patch please review it .

luke.stewart → made their first commit to this issue’s fork.

That patch seems to be wrong. I've created an Issue fork done the rename and pushed.

Hopefully this is easier to review.

> but I guess the post update step won't run like this.

If it does I think this is a problem!

Looks good to me, thanks.

However, I don't know how this script gets called and whether there need to be any further changes in some script(s) calling it.
