[FR] Include Related Integrations and Setup information for prebuilt ML Rules

[spong]

In line with elastic/security-docs#2974, this issue is intended to help users better understand which integrations and what prior setup may be required to successfully use our Prebuilt ML Jobs/Rules.

Please touch base with the @elastic/security-ml folks for specifics on which rules require which integrations, and any additional setup instructions that may be required.

Once added, the Related Integrations and Setup fields will then be visible to the user within the security app as follows:

Note: not sure if required fields are relevant here as well too, or if integrations/setup will suffice. Please discuss further with the ML folks for their thoughts here.
