Documentation issues: non-existing flags

[ralfbergs]

In the README.md for the current version, 0.7.0 / 2025-03-14 Latest, it mentions in section Relation to Node and Process Exporter the below flags:

• --systemd.collector.enable-task-metrics
• --systemd.collector.enable-restarts-metrics
• --systemd.collector.enable-start-time-metrics

In a later section, Systemd versions, it mentions the below flags:

• --systemd.collector.enable-restart-count
• --systemd.collector.enable-file-descriptor-size
• --systemd.collector.enable-ip-accounting

It seems that the below flags refer to the same thing, maybe they have changed over time?

• --systemd.collector.enable-restarts-metrics
• --systemd.collector.enable-restart-count

The flags actually implemented in that version on my system are:

$ /usr/local/bin/prometheus-systemd-exporter --help 2>&1 |grep systemd.collector.enable
      --[no-]systemd.collector.enable-restart-count
      --[no-]systemd.collector.enable-ip-accounting
      --[no-]systemd.collector.enable-resolved

Which would mean that --systemd.collector.enable-restart-count is probably the correct option, while --systemd.collector.enable-restarts-metrics might be an outdated one?

Furthermore, --[no-]systemd.collector.enable-resolved is not documented in the README.md -- not sure if this is an oversight or intentional?
