* [telegraf] Fix: Cannot define inputs without health check

In the current implementation, a misplaced `{{- end }}` in the chart causes the `{{ template "inputs" .Values.config.inputs -}}` call to be inside the `{{- if .Values.metrics.health.enabled }}` conditional block.

This fixes that.

* Update Chart.yaml with a new version number

Bump the version and add a sources list.

* s/values/Values/

* bump chart version

* fix indentation count s/6/8/

* Update configmap.yaml

* chart version bump

* fix: remove string comparison for boolean

* fix: version bump

Setting 'create' to 'true' as it's generally wanted, but now the flag
exists so it can be skipped. I tested this locally with both options to
make sure it worked, and I copied the naming from influx1's chart, but
feel free to make changes as necessary.

While the PR has been open, the verion number got bumped forward, and I
needed to bump it again to clear lint. So I rebased and force-pushed my
branch to make it clear.
