Helm chart default telemetry config causes router to crashloop

[vatsalpatel]

Describe the bug

The expcted configuration is telemetry.exporters.metrics.common.resource.service.name, which is correct if exporters are provided.
However, when exporters are not provided, the mistake in helm chart causes the resource part of the config to become resources
Above only causes a configuration warning, but the server doesn't start with the following error
could not create the HTTP server: Permission denied (os error 13)

Here is the part that needs to be fixed:
In the file https://github.com/apollographql/router/blob/dev/helm/chart/router/templates/configmap.yaml, line 8 needs to be
{{- $configuration := dict "telemetry" (dict "metrics" (dict "common" (dict "resource" (dict "service.name" $routerFullName)))) -}}

To Reproduce

Steps to reproduce the behavior:
Install router through helm without specifying any telemetry configurations

Expected behavior

The server starts normally

Additional context

We are upgrading the router from v1.20.0. WIthout changing our config, it works until v1.33.0, from v1.34.0 it starts breaking.
v1.34.0 happens to be the version where the config change was made. It doesn't work on latest version either due to the mistake in helm chart
