Add anti affinity to the Mina Daemon Helm Chart

[kaozenn]

** Problem **
To prevent pods (Mina Nodes) from being scheduled on the same Node, we need to implement Pod Anti-Affinity. Consequently, a Pod cannot be scheduled on a node that already hosts another Mina Node.

This measure is of utmost importance because in the event of an EC2 Instance crash or upgrade, maintaining the uptime and operation of the Mina Network remains paramount.
