Social Menu & Social Media Icons: Add Vero Support

### Impacted plugin

Social

### What

The addition of the social media platform Vero to the Social Links Menu block.

### How

The [Wikipedia article](https://en.wikipedia.org/wiki/Vero_(app)) for Vero describes the social media network as,

> Vero (stylized as VERO) is a social media platform and mobile app company.[4][5] Vero markets itself as a social network free from advertisements, data mining and algorithms.[6]

We received a request for the support/addition of this icon for the [Social Icons Block](https://wordpress.com/en/support/wordpress-editor/blocks/social-links-block/).

Please consider this addition if possible. Thank you.

Start by locating the Social Links Menu block and the Social Icons Block entry points, then compare how existing social platforms are represented and tested. Done means Vero is available as a selectable social platform with its icon displayed correctly.
