Update Openverse symbol and color

[fcoveram]

Nowadays, Openverse has a solid brand documented mostly in the Design Library (​https://www.figma.com/file/GIIQ4sDbaToCfFQyKMvzr8/Openverse-Design-Library?node-id=0%3A1) and it would be great to update the icon and main color defined for the profile badge (​https://make.wordpress.org/meta/handbook/tutorials-guides/profile-badges/) since those are outdated.

Here is attached the SVG file of the symbol, and the new hex color is #C52B9B

This has been updated on profiles - you can see the new icon on ​fcoveram :)

The ​profile doc has also been updated.

I'm switching the component to Make now, because the search icon is still used on the Make network (for example, ​https://make.wordpress.org/openverse/, ​https://make.wordpress.org/). That might need a little more thought, since it's set to use a dashicon in multiple places (wp4.css, wporg-makehome theme), and ideally the SVG would be inlined to inherit the link state colors.

Breathe: Use SVG icon for Openverse and Performance team sites.
