[Component] What is Open Source Explorers (3-up, text)

[hcavanaugh]

Design: See this Figma file.

Code:

• Create the src/components/ose-program/OSE-3up-text.tsx file.
• Create or a shared component for the circle, should be contained in src/components/ose-program/ See [Component] OSE timeline #370

Notes:

• Since we're making a new page with a significantly different design than the old one, there shouldn't need to be too much code reuse. Let's prioritize using Radix UI components (check both their Theme and Primitives docs). It's ok to sprinkle in some tailwind in order to go above and beyond what we get out of the box with Radix, but don't feel like you need to be pixel-perfect when following the designs.
