Chore: Fix deployment types in telemetry

[marcleblanc2]

Description

Linear issue REL-812: Update deployment types

Instances with deployment type "Kubernetes" are too vague to be useful in telemetry. Setting this now, so that we can start identifying these usefully in Telemetry as customers upgrade their legacy Kustomize instances >= 6.2.0

NOTE:

Checklist

• CHANGELOG.md updated
• K8s Upgrade notes updated
• Sister deploy-sourcegraph-k8s change:
• Sister deploy-sourcegraph-docker change:
• All images have a valid tag and SHA256 sum
• I acknowledge that deploy-sourcegraph-k8s is now the preferred Kubernetes deployment repository

Test plan
