Pages: style the 'suggested addition' to favorites like a suggested addition

[ruggi]

The 'suggested addition' looks too much like a regular but disappearing entry.

Solution:

• [x] font-style: italic, backgroundColor: moreSubdued (we don't have this I think, light mode a 98% worked well.
• [ ] while there, make the star icon use a more subdued color as well,
• [ ] check if we're using the interpolated version of italic-inter or the real one, by adding the italic 400 - 600 variants and seeing if that changes the rendering.

Intended result for the font-style only (not the other two checkboxes)

@lankaukk I did the first (easy :D) part in https://github.com/concrete-utopia/utopia/pull/5298 - would you mind taking the other two experiments? I think your eyes would probably work better than mine
