What did you do?

After updating Prometheus to 2.48.0, Spring Boot Actuator metrics are no longer being collected.

What did you expect to see?

It should also work correctly with 2.48.0.

What did you see instead? Under which circumstances?

Before 2.47.2, the following Accept headers were sent

application/openmetrics-text;version=1.0.0,application/openmetrics-text;version=0.0.1;q=0.75,text/plain;version=0.0.4;q=0.5,*/*;q=0.1

In 2.48.0, the following Accept header is sent, but */*;q=2 is incorrect, resulting in an error in Spring Boot.

application/openmetrics-text;version=1.0.0;q=0.5,application/openmetrics-text;version=0.0.1;q=0.4,text/plain;version=0.0.4;q=0.3,*/*;q=2

Quality Values is incorrect because it ranges from 0 through 1.
