Upgrade prometheus-nginxlog-exporter role (v1.10.0-4 -> v1.10.0-5) and fix its metric names

Browse Source 
The exporter's configuration used to ship a leftover "myprefix" placeholder
as the metric name prefix, so the bundled Grafana dashboard (which queries
unprefixed metric names) could never show any data.

Metric names are now unprefixed and the namespace label value changed from
matrix to nginx. See the CHANGELOG entry for details.

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/3380

## prometheus-nginxlog-exporter metric names have changed
If you have enabled [metrics for nginx logs](docs/configuring-playbook-prometheus-grafana.md) (`prometheus_nginxlog_exporter_enabled: true`), note that the exporter's metric names have changed.
The exporter's configuration used to ship a leftover `myprefix` placeholder as the metric name prefix, producing metrics like `myprefix_http_response_count_total`. The bundled Grafana dashboard queries unprefixed metric names (`http_response_count_total`), so it could never show any data (reported in [#3380](https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/3380)).
Metric names are now unprefixed, matching the bundled dashboard, which should start working. Each metric carries a `namespace` label, whose value is now `nginx` (previously `matrix`); it is configurable via `prometheus_nginxlog_exporter_config_namespace_name`. If you have built custom dashboards or alerts on top of the old `myprefix_*` metric names, adjust them accordingly, or restore the old behavior by setting `prometheus_nginxlog_exporter_config_namespace_metrics_prefix: myprefix` in your `vars.yml` file.
