This is quite subjective, but I think it looks nicer if there is also an icon for informational entries
One could use icon-info instead as it looks a bit nicer, but it doesn't fit the style of the other icons.
Also there don't seem to be a LESS variable for the error/warning/info/sucess colors, so I copied the ones from notifications over.
If you are interested I could create a PR unifying them over all of Matomo.
These are the before-after screenshots, to make it easier to decide which one is preferred:
If someone doesn't like the icons in the informational results we could maybe remove them just there
All good 👍
Just noticed while updating tests that there is a separate CSS file for the installer.
