INI was not able to parse metrics.addr

[dpliatsios]

I have built the latest gnb and I try to export the metrics to Grafana, but I receive the following error when starting gnb:

--== srsRAN gNB (commit 11c9bbabb6) ==--

INI was not able to parse metrics.addr
Run with --help for more information.

Please find below the relevant metrics section in the config.yml:
