otel: update breaking changing apis

[jsign]

Summary

This PR updates the OTEL dependencies, which have breaking APIs, and other deps.

Note: This PR will be a draft until open-telemetry/opentelemetry-go#3229 gets fixed in the next OTEL version. This is blocking because otelsql relies on OTEL deduping re-registering metrics; if that invariant doesn't hold, it causes a panic. We'll wait until there's a new OTEL version, and see how everything works.

After the problem above was fixed, there were two other breaking changes:

• service_name and other satellite attributes aren't automatically added to metrics. This is now fixed with a metrics.BaseAttrs that should be used in other baseAttrs slices.
• Under the new OTEL semantics, the "official" OTEL runtime package has a bug in defining multiple metrics as UpDownCounter instead of Gauge. That package has more logic than what we need, so I did a direct implementation of the metrics that interest us and removed the dependency,.

I also added an Uptime tile:

Memory metrics now show both api and healthbot series.

Context

We were notified by dependabot that new dependency versions were available.

Implementation overview

The OTEL breaking changes were a bit annoying since there's no documentation on how to fix them.
I had to do some GH search and code reading to figure out how to fix this properly.

Implementation details and review orientation

I slightly modified the bucket numbers to have extra buckets between the 10ms and 100ms range.
