High availability is not supported for Temporal server

### Helm Chart Version

2.0.16

### What step the error happened?

On deploy

### Relevant information

The Airbyte Helm chart includes an [option](https://github.com/airbytehq/airbyte-platform/blob/f5f77fd46f2de910201ac55c497edcfd59d96c57/charts/v2/airbyte/templates/airbyte-temporal/deployment.yaml#L15) to run multiple replicas of the Temporal server, however this is impractical due to the lack of support for Temporal's [clustering capabilities](https://docs.temporal.io/references/configuration).

This deployment should be brought closer to parity with Temporal's Helm chart by:
* Including configuration options for server membership in the [server configmap](https://github.com/airbytehq/airbyte-platform/blob/f5f77fd46f2de910201ac55c497edcfd59d96c57/charts/v2/airbyte/templates/airbyte-temporal/configmap.yaml)
* Exposing additional ports for member discovery in the [server deployment](https://github.com/airbytehq/airbyte-platform/blob/f5f77fd46f2de910201ac55c497edcfd59d96c57/charts/v2/airbyte/templates/airbyte-temporal/deployment.yaml#L86-L87)

The official [Temporal Helm chart](https://github.com/temporalio/helm-charts/tree/main) may be used as a reference.

Alternatively, the `temporal.replicaCount` value should be removed and replaced with a fixed value of 1. Documentation should also be updated to indicate that this chart does not support a "production-ready" deployment by most measures out of the box, and offer alternative solutions.
