Telemetry and Healthcheck path without slash does not work

[ToMe25]

Using the argument web.telemetry-path or web.healthcheck-path with a path that is not prefixed with a slash results in said page not being reachable at all.
The "Not Found" page still tries to link to it, but said link just leads you to the "Not Found" page again.

In my opinion such a path should be, silently or with a log warning, prepended with a slash.

Feel free to tackle this. I'll keep the issues open. But at the moment I don't have capacity to work in this exporter apart from occasional maintenance.

I opened these recent issues mostly to track these things, I don't consider them to have any significant urgency.

I will look into implementing some of them if and when I find the time and motivation to do so :)
