Quarkus redirects creates new trace and span and I can't link them as a parent

[ukrcoder]

Using quarkus 3.4.3 and latest opentelemetry there. I want whole my flow be linked and to see it inside zipkin/jager (no matter). But whan I have redirects in my code -> than I
ll always have separate track and new traceId flow.
I cannot always pass traceparent header because of ui (in that case secured cookies could be used so I can store state). But adding as a header doesn't help to link to the parent.

Tried to add parent to the context with next code
`String[] values = traceparentCookie.split("-");

        SpanContext parentContext = SpanContext.create(values[1], values[2], TraceFlags.getSampled(), TraceState.getDefault());
        Span parentSpan = Span.wrap(parentContext);
        Log.infof("TRACEPARENT DATA: trace is = " + values[1] + " and span is = " + values[2]);

        Span span = tracer.spanBuilder("ui-provider-picker").setParent(Context.current().with(parentSpan)).startSpan();
        try (Scope scope = span.makeCurrent()) {
        } finally {
            span.setAttribute("test", "12345");
            span.end();
        }`

it creates new span and attaches to base process as a last one and then starts new trace with needed me endpoint. It's also created as an empty one without tags or any info.

Overall what I want: to link one span with another one retrieving all needed tags. Couldn't find solution meanwhile.
Any suggestions?

I'm going to transfer this to the instrumentation repository, since it seems to be related to how to write quarkus-friendly instrumentation for redirects.
