[Internal]: Remove list of "Beta agentless integrations" from security/get-started/agentless-integrations

[cpascale43]

Description

We should rework the list of agentless integrations in beta - we are continuously adding more of these, so a list of each one may be misleading/gunwieldy to maintain.

We could remove the section entirely, or keep a generic beta callout.
