Steps to reproduce:

1. Install Zabbix LTS 6.0+
2. Try to configure SAML/SSO with Azure AD 
3. Configure Azure part with request signing enforcing
4. Open documentation, example exists only for 6.4+: https://www.zabbix.com/documentation/current/en/manual/appendix/install/azure_ad
5. Try to configure as described without JIT for 6.0.

Result:

1. No access

Expected:

1. Documentation provides steps required for request signing (create certificates, enable them inside configuration file).
2. Documentation provides same examples for LTS 6.0 and LTS 6.4+, since SAML/SSO auth is the same between versions, except JIT provisioning.
3. Documentation provides good quality screenshots/examples, not like from 640*480 screen era.
