[FIX] web_editor: adapt color of svg support rgba with space

Before this commit, we only support rgba(xxx,yyy,zzz,v.www)
Now we support also rgba(xxx, yyy, zzz, v.www)

How to reproduce:
Edit theme color secondary, chose a color with transparency.
Go to a 404 page and the pinky will be not loaded.
