Docs: `securityContext` missing for multiple resources in the API Reference

[DodoLeDev]

Which document needs to be updated? The API Reference of the Redis Operator

Actually, the Redis(Cluster/Replication/Sentinel)Spec is using the unfunctional securityContext field

Expected changes

What version of redis-operator are you using?

I am talking about the v1beta2 of the API

Additional context Related issue: #1345

Additionnally, the securityContext field is not specified in the RedisLeader ¹ and RedisFollower ² resource.

And the field present in the RedisExporter resource is not a PodSecurityContext, but a SecurityContext.
