Search: Fix whitespaces

Using strip_newlines formatted content into (notice the missing whitespaces):

Instead, you can configure kamal-proxy under proxy.If you were using custom Traefik labels or args, see the proxy configuration to determine whether you can convert them.Be aware that by default kamal-proxy forwards traffic to the container port 80, this is because we assume your container is running Thruster, and it listens on the port 80. If you are running a different service or port, you can configure the app_port setting:proxy:  app_port: 3000kamal-proxy supports common requirements such as buffering, max request/response sizes, and forwarding headers, but it does not encompass the full breadth of everything Traefik can do.If you don’t see something you need, you can raise an issue and we’ll look into it, but we don’t promise to support everything — you might need to run Traefik or another proxy elsewhere in your stack to achieve what you want.HealthchecksThe healthcheck section has been removed.Proxy rolesFor roles running with a proxy, the healthchecks are performed externally by kamal-proxy, not via internal Docker healthchecks. You can configure them under proxy/healthcheck.proxy:  healthcheck:    path: /health    interval: 2    timeout: 2Please note that the healthchecks will use the app_port setting, which defaults to port 80.

Replacing it with normalize_whitespace yields:

This change fixes two things:

1. Fix search for some terms

Lunr does do substring matching, but only with the end of a string (source)

So searching for deploy_timeout didn't match any pages because it was indexed as bootdeploy_timeout instead of boot deploy_timeout (see content strings above).

2. Fix previews in search page
