confighttp ErrorLog update

[sonalgaud12]

Description

Added Zap as the default error logger in confighttp.ToServer() to ensure consistency in logging and to prevent errors from being printed using a different logger. This change configures the ErrorLog field of the http.Server to use a logger backed by Zap, which is initialized with the provided logger in TelemetrySettings. If the logger creation fails, the function now returns nil, err to prevent any undefined behavior from occurring due to an incomplete setup of the logger.

Fixes #11820

Documentation
