* docs: Update netlify deploy readme for clarity
It was unlcear why "Gatsby" was mentioned in the env name for the server URL. Also, the code shows precedence given to `MEDUSA_BACKEND_URL` now:
```
__MEDUSA_BACKEND_URL__: JSON.stringify(
env.MEDUSA_BACKEND_URL ||
// Backwards-compat with Gatsby.
env.GATSBY_MEDUSA_BACKEND_URL ||
env.GATSBY_STORE_URL ||
""
),
```
Therefore, this should be indicated in the documentation.
* Update docs/content/deployments/admin/deploying-on-netlify.md
* Update deploying-on-netlify.md
