UriInfo.getBaseUri ignores prefix header handling

[shawkins]

Describe the bug

If you set quarkus.http.proxy.enable-forwarded-prefix=true and specify an X-Forwarded-Prefix header, that will not be reflected in getBaseUri - but will be present in the UriInfo.getRequestUri and UriInfo.getAbsolutePath.

Expected behavior

getBaseUri should have the prefix pre-pended.

Actual behavior

The prefix is omitted.

How to Reproduce?

With:

quarkus.http.proxy.proxy-address-forwarding=true
quarkus.http.proxy.allow-x-forwarded=true
quarkus.http.proxy.enable-forwarded-host=true
quarkus.http.proxy.enable-forwarded-prefix=true

Submit a request with the header "X-Forwarded-Prefix: prefix" and observe the base uri for the request does not reflect the prefix.

@froque unfortuantely it is not. The getBaseUri behavior is happening against quarkus 3.27.0.

At first glance, the LocationUtil logic that was added in that fix, needs to be incorporated into org.jboss.resteasy.reactive.server.jaxrs.UriInfoImpl.getBaseUri. cc @geoand

@shawkins sounds reasonable. Do you want to open a PR?

Sure, I can take a stab at it.
