Remove redundant space after enum/flags word in editor docs

Just cosmetic change, I think it's a typo?

I don't believe that was a typo as it makes the name more distinct but it's... whatever

RST docs use one space:

Again, I don't think it was an accident since it's difficult not to notice it, but I do not mind the change

I'm fine either way. I also imagine this was done on purpose to have more separation between the keyword and the enum name, but it's pretty arbitrary. Since we don't have it in the online docs and it looks fine, I think we can go for consistency.
