[Feature Request] Support passing ImagePullSecrets to Temporal Web Deployment Helm Template

[mustaFAB53]

Is your feature request related to a problem? Please describe.

Temporal web Kubernetes deployment manifest / helm template do not support passing imagePullSecrets. A support needs to be added for the same as temporal web images can be expected to be fetched from private registries

Describe the solution you'd like

Add required support similar to the one already provided in temporal server deployment manifest
