lib/promscrape: properly implement ScrapeConfig.clone()
...
Previously ScrapeConfig.clone() was improperly copying promauth.Secret fields -
their contents was replaced with `<secret>` value.
This led to inability to use passwords and secrets in `-promscrape.config` file.
The bug has been introduced in v1.77.0 in the commit 67b10896d2https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2551
