Proposal

Adds the "Extend > Icons" page based on:

• the previous corresponding Boosted page (see code source)
• the corresponding Bootstrap page (see code source)

The Entry "Solaris Icons" in Boosted horizontal navigation could also be added in OUDS with following url : https://oran.ge/icons

Motivation and context

Being functionally equivalent to Boosted :)
Icons are very often used by designer and user.
