Configure policies - add visibility

[osokin]

Describe the bug

The following command has limited visibility.

sudo docker run --rm -v $(pwd):$(pwd) --entrypoint='' private-registry.nginx.com/nap/waf-compiler:1.0.0 cat /etc/app_protect/conf/NginxStrictPolicy.json

It's better to use a backslash symbol to reduce number of symbols in a line, i.e.:

sudo docker run --rm -v $(pwd):$(pwd) \
    --entrypoint='' \
    private-registry.nginx.com/nap/waf-compiler:1.0.0 \
    cat /etc/app_protect/conf/NginxStrictPolicy.json

To reproduce

Steps to reproduce the behavior:

1. Open https://docs.nginx.com/waf/policies/configuration/#strict-policy
2. View output
3. See issue

Expected behavior

A clear visibility of the command needs to run.
