Fix prometheus test ipv4

[Tusharika725]

Fixes #8148

Updates the createMetricReader_Default test in PrometheusMetricReaderProviderTest to correctly handle both IPv4 and IPv6 wildcard addresses.

What happened?

Previously, the test strictly asserted that the local server bound to the IPv6 wildcard address (0:0:0:0:0:0:0:0). On certain environments (like Red Hat Enterprise Linux) where IPv6 is disabled or deprioritized, the JVM falls back to the IPv4 wildcard (0.0.0.0). This caused the test to fail despite the underlying web server functioning perfectly.

The Fix

Updated the AssertJ assertion to use .isIn() to accept any valid wildcard address (0:0:0:0:0:0:0:0, 0.0.0.0, or ::), ensuring the test passes consistently across different OS network configurations.

All local tests and spotlessCheck formatting are passing.

Pull request overview

Updates the Prometheus exporter default-server test to be resilient across environments that bind the HTTP server to either IPv4 or IPv6 wildcard addresses.

Changes:

• Relaxes the createMetricReader_Default assertion to accept multiple wildcard address string forms (IPv4 + IPv6).
• Keeps the existing port assertion to ensure the default endpoint remains unchanged.
