docs(docker): add instructions on how to serve over HTTPS

* Added a script to generate a self-signed certificate
* Added *.pem, *.key and *.crt files to .gitignore and .dockerignore
* Stopped setting PUB_PLAUSIBLE_URL to https://plausible.example.com on Docker Compose builds by default
* Modified "Building on Production" to mention that HTTPS is required on most cases
* Added a base HTTPS config for nginx

+#### Pulling instead of building
 
 While there's an image you can pull instead of cloning the repo and building the image yourself, you will not be able to update any of the environment variables (e.g. `PUB_PLAUSIBLE_URL`) as they're baked directly into the image and not obtained during runtime. If you're okay with this, you can simply run this command instead:

+#### Serving the site over HTTPS
+
+If you're running the container in your local machine and accessing it from `localhost`, this isn't really required. However, any other origin will cause cross-origin
+isolation to be disabled unless you serve the site over HTTPS, which in turn will cause image conversions to fail. There are a few options to get around this:
+- Using something like Tailscale's [HTTPS feature](https://tailscale.com/kb/1153/enabling-https)
+- Using a self-signed certificate (not recommended for public instances and your browser will likely yell at you)
+- Using Let's Encrypt or Cloudflare as a TLS proxy with your own domain
+
+If you want to use a self-signed certificate, there's a little [script](./nginx/setup-self-signed.sh) you can run in order to generate one. Make sure you have `openssl` installed, then run:
+```shell
+$ cd ./nginx/
+$ ./setup-self-signed.sh
+```
+
+This will generate the following files inside `./ssl/`:
+```shell
+$ ls ./ssl
+self-signed.crt  self-signed.key
+```
+
+If you don't want to use a self-signed certificate, simply copy your own key and certificate files into `./nginx/ssl/` instead. Make sure to then modify the default SSL config under [./nginx/default-ssl.conf](./nginx/default-ssl.conf) to match the file names:
+```conf
+server {
+    ...
+
+    ssl_certificate     /etc/ssl/vert/self-signed.crt;
+    ssl_certificate_key /etc/ssl/vert/self-signed.key;
+
+    ...
+}
+```
+
+Finally, update your Docker Compose configuration:
+```yaml
+services:
+  vert:
+    # ...
+    ports:
+      # map to port 443 instead of 80
+      - "${PORT:-3000}:443"
+    volumes:
+      # map the ssl folder with our certificates to /etc/ssl/vert in read-only mode
+      - "./nginx/ssl:/etc/ssl/vert:ro"
+
+      # overwrite the default HTTP configuration of the container
+      - "./nginx/default-ssl.conf:/etc/nginx/conf.d/default.conf"
+```
+
+For `docker run`, use:
+```shell
+$ docker run ... \
+	-p 3000:443 \
+	-v "./nginx/ssl:/etc/ssl/vert" \
+	-v "./nginx/default-ssl.conf:/etc/nginx/conf.d/default.conf" \
+	...
+```
