Fixed HTTP bridge related Prometheus rules

Description

It seems that since Vert.x 4.x the naming convention for the metrics related to the HTTP server requests total changed.

In previous version Vert.x 3.x it was using requestCount as per here https://github.com/vert-x3/vertx-micrometer-metrics/blob/master/src/main/java/io/vertx/micrometer/MetricsNaming.java#L167 so the exposed metric was strimzi_bridge_http_server_requestCount_total.
From Vert.x 4.x it has been using "requests" as per here https://github.com/vert-x3/vertx-micrometer-metrics/blob/master/src/main/java/io/vertx/micrometer/MetricsNaming.java#L211 so the exposed metric is strimzi_bridge_http_server_requests_total.

It means that the current provided Prometheus rules using old strimzi_bridge_http_server_requestCount_total are not working anymore and they should use strimzi_bridge_http_server_requests_total instead.

This was raised via strimzi/strimzi-kafka-bridge#1034
