Vite migration

[fdodino]

#363

• Actualizar las dependencias (casi listo, porque no vamos a laburar con Mocha, Chai, Sinon ni NYC)
• Migrar a ESLint 9 con flat config
• Usar LTS 22 de Node en un .nvmrc
• Reemplazar ts-node por tsx
• Migrar a vitest (falta el parser.test.ts + matchers del parser)
• Usar ESM -> está bravo, hay varias cosas que se rompen mal (la definición de nodeCache, el import de JSON)

Ojo:

• no se puede usar TS más allá de 5.4.5 porque con decorators se rompe mal
• no podemos migrar a yargs 18 hasta que no pasemos a ESM
