chore: local api server

[holloway]

chore

• Red's website pulls JSON from precomputer files uploaded to rfc-editor.org/api/...  which has meant that, when prototyping changes, I merge them, run tekton, and try the website again. This is slow and the dev feedback loop takes ten minutes or so. So instead i'm adding a precomputer dev server that can serve those APIs locally

fyi @jennifer-richards when running the website locally in local development mode (ie npm run dev) it now uses a local api dev server which the precomputer serves. This is now the default config, and this replaces the existing approach of using staging/prod APIs only. This will improve the dev feedback loop.

You can still easily swap back to the previous approach by uncommenting those proxy: lines in nuxt.config.ts and there's a docstring added about this.
