Add helia

[ElPaisano]

This PR adds Helia to the project so that we can create Helia tutorials.

TLDR;

can import helia, local build works, created a lesson using protowizard, but cant figure out how to actually use Helia in the lessons without causing build errors. Also, staging build is failing

Steps:

1. cd into project
2. npm install helia -> adds to package.json
3. open Lesson.vue
4. Add helia
   • as global (line 205)
   • modules (line 178)
   • eval function (line 172)
5. npm start -> actually works, wasn't working when I tried to import helia
6. create helia 101 lesson
7. Verify helia appears on line 1 of code editor in lesson /* global ipfs, helia, all, toBuffer */
8. Try to create a node
   • can't `import { createHelia } from "helia"' without error
