feat(users/Profpatsch): Implement initial otel-dbus proxy r/8998

For simplicity’s sake this puts everything into the
alacritty-change-color-scheme script for now.

This implements a simple dbus-opentelemetry proxy adapter, which
allows services to record otel traces without having to depend on the
quite complex otel libraries. Instead, they just send their traces to
the dbus tracing interface, and the service that binds against that
interface forwards the spans to the OTLP collector.

First you create a new Tracer for your service via the `TracerFactory`
interface:

```
> busctl --user call \
    de.profpatsch.otel.Tracer \
    /de/profpatsch/otel/TracerFactory \
    de.profpatsch.otel.TracerFactory CreateTracer \
    s hello
s "/de/profpatsch/otel/tracers/hello"
```

(this corresponds to setting up a tracer with properties in OTEL)

Then, you can use the returned object path to call the `Tracer`
interface proper:

```
< busctl --user call \
    de.profpatsch.otel.Tracer \
    /de/profpatsch/otel/tracers/hello \
    de.profpatsch.otel.Tracer \
    StartSpan \
    s '{"spanId": "111", "name": "111"}'
```

This will create the spans. You can also set their timestamps on the
sending side via `startTime`/`endTime`, but make sure it’s a hrtime
tuple.

Prefer batching multiple spans vie the `BatchSpans` call.
