fix(docs): Make viewing (outdated) protocol specs work locally (#13534)

Viewing the protocol specs pages currently (with `yarn dev` or `yarn
dev:local` in ./docs) currently doesnt work because the versioned docs
do not include the protocol specs pages. This PR disables versioning for
viewing protocol specs pages locally, so it will work.

 A new docs site is published on every merge to the master branch, if there are any changes in the docs folder. You can also manually trigger a new deployment by running the `docs-deploy` workflow in the [Github Actions tab](https://github.com/AztecProtocol/aztec-packages/actions/workflows/docs-deploy.yml). This can be triggered from a branch and does not have to wait for a PR to be merged, although merging a PR is recommended.
 
+## Viewing (outdated) protocol specs

+To view the protocol specs, you can run `yarn dev` or `yarn dev:local`. When viewing the protocol specs locally, versioning is disabled, so you can view the protocol specs in the browser. It would error otherwise because the protocol specs pages are not included in the pages in `versioned_docs` and `versioned_sidebars`.
