Increase Sero's Stream by 300 USDC and 40K RIC

Context:

Sero has been responsible for managing communications, handling grant requests, frontend development, and social media/community management.

One of our contributors who was responsible for Frontend development is taking a break, he had a stream of 300 USDC and 40K RIC allocated to him for fixing bugs, developing features and improving UI.

What

Redirect that stream to Sero, to spend more time on Frontend Development.

Why

We are constantly improving and maintaining Ricochet Exchange, and are currently building Ricochet Pro. Sero has been with the team for over a year and is knowledgable about the codebase, and needs of the organization.
