Old page with broken layout

[mikelittle]

This page is old and unstyled. https://docs.altis-dxp.com/security/limit-login-attempts/ It should be removed and ideally a redirect in place to /security/

---

Acceptance Criteria

• [ ] The page should redirect to /security
• [ ] Alternatively, just deleted.

[rmccue]

Maybe we want a redirect to https://docs.altis-dxp.com/guides/upgrading/v7/#limit-login-attempts-removed ?
