Vercel deployment is currently broken because of this error:

error: TypeScript files are not supported in npm packages: file:///vercel/path1/.vercel/builders/node_modules/vercel-deno/dist/runtime.ts
Error: Build script failed with exit code 1

The fact that the default version is stuck on 1.x and the codebase is on 2.x is definitely troublesome too (vercel-community/deno#159)

Might be better to switch to deno deploy, though it'd need to be done in the ci because there's no build steps on deploy
