Update Dockerfile to work with Next.js (#12119)

* Update Dockerfile to work with Next.js

- Update to Node 18
- Do not run as root, this also works better with Node
  privilege-dropping.
- Update README with new run instructions and adding the
  `--rm` flag to avoid leaving a bunch of unused Docker
  containers.
- Also change README to recommend building the image locally.
  Image builds are pretty fast and the uploaded images get
  outdated pretty quickly.

* Add .dockerignore to avoid sending large build contexts

 `node_modules` folder**, since there are some dependencies that need to be built
 for the image system. Rename it before using.
 
-```bash
-docker run -it \
-  -v $(pwd):/spacy-io/website \
-  -p 8000:8000 \
-  ghcr.io/explosion/spacy-io \
-  gatsby develop -H 0.0.0.0

-This will allow you to access the built website at http://0.0.0.0:8000/ in your
-browser, and still edit code in your editor while having the site reflect those
-changes.
-
-**Note**: If you're working on a Mac with an M1 processor, you might see
-segfault errors from `qemu` if you use the default image. To fix this use the
-`arm64` tagged image in the `docker run` command
-(ghcr.io/explosion/spacy-io:arm64).
-
-### Building the Docker image
-
-If you'd like to build the image locally, you can do so like this:
+First build the Docker image. This only needs to be done on the first run
+or when changes are made to `Dockerfile` or the website dependencies:
 
 ```bash
 docker build -t spacy-io .
 ```
 
-This will take some time, so if you want to use the prebuilt image you'll save a
-bit of time.
+You can then build and run the website with:
+
+```bash
+docker run -it \
+  --rm \
+  -v $(pwd):/home/node/website \
+  -p 3000:3000 \
+  spacy-io \
+  npm run dev -- -H 0.0.0.0
+```
+
+This will allow you to access the built website at http://0.0.0.0:3000/ in your
+browser, and still edit code in your editor while having the site reflect those
+changes.
