[AppSec] Updates

[LaurenceJJones]

I will be adding all issues I find within appsec docs so we can properly track these:

• [x] appsec-config default_remediation is ban but what options are there? link
• [x] appsec-config default_pass_action is nothing but what options are there? link
• [x] appsec-rules equals or equal link however example has equals link
• [x] Hooks are not just strings but struct we should provide example how to write them

Missing items:

• [ ] How to import native modsec rules (ie. dedicated page)
• [ ] Link to how to use your own rules in the quickstart page

• [x] appsec-config & hooks : only "special" remediation is allow. Everything else (including ban and captcha) is passed "as is" to the bouncer
