Broken-a$$ links

[LauraLangdon]

Even though I added a link checker to the docs workflow in PR #114, the Algolia crawler found 18 links that lead to 404 errors. Here's the list:

• [ ] https://docs.suborbital.dev/grav/introduction/concepts/reciepts.md
• [ ] https://docs.suborbital.dev/integrate-the-function-editor/code-editor
• [ ] https://docs.suborbital.dev/test-project
• [ ] https://docs.suborbital.dev/grav/usage/getting-started/
• [ ] https://docs.suborbital.dev/atmo/concepts/(../runnable-api/introduction)

• [ ] https://docs.suborbital.dev/meshing/discovery/
• [ ] https://docs.suborbital.dev/compute/quickstart/1.-create-an-environment-token-with-subo.md

I'll fix these links and create a separate issue to figure out why the link check in the workflow didn't catch these.

These will all be addressed in a very-near-future docs release.
