Some of the icons on the standard toolbar have indistinguishable appearance

[rizmut]

Insert Field, Insert Endnote, Insert Footnote, Insert Reference, Show Track Change Functions has similar appearance and so it's hard to distinguish them

Comparing this to other icon themes: Colibre: elementary: Karasa Jaga: Sifr: Sukapura:

It would be nice if those icons get refinement, eg. make the orange part thicker or change the shape. Whatever the best for Yaru.
