Backport 31a1314 from #12982
What this PR does / why we need it:
Example is broken.
Special notes for your reviewer:
Without the added quotation marks, the following error is thrown:
"failed parsing config: /etc/loki/config/config.yaml: Use
-config.expand-env=true
flag if you want to expand environment variables in your config file"So without this change, the examples are not working properly.
In https://grafana.com/docs/loki/latest/operations/storage/tsdb/ the quotation marks are also used.
