chore: update deps to fix build issue (prettier)

[palmerabollo]

Añade "prettier" a las devDependencies de la web. Es una peer dependency de @vue/eslint-config-prettier y sin ella da este error al hacer npm run start, siguiendo los pasos del README:

npm run start

> verba-volant@1.0.0 start /Users/guido/verba
> run-p start:api start:web

> verba-volant@1.0.0 start:api /Users/guido/verba
> npm run start --prefix api

> verba-volant@1.0.0 start:web /Users/guido//verba
> npm run start --prefix web

> verba-volant-api@1.0.0 start /Users/guido/verba/api
> nodemon --exec babel-node src/index.js

> verba-volant-web@1.0.0 start /Users/guido/verba/web
> vue-cli-service serve

[nodemon] 2.0.6

Syntax Error: Error: Cannot find module 'prettier'

Además elimino la dependencia run-p del package.json principal. Es un alias que instala npm-run-all, no es necesario indicar esa dependencia.
