gzlog prints msgs as [error]

[iche033]

Environment

• OS Version: 24.04
• Source or binary build? source, gz-common6

Description

• Expected behavior: In gz-common5, the gzlog msg does not get printed to the console but only gets logged to the ~/.gz/auto_default.log
• Actual behavior: Use of gzlog prints msgs to console as [error] which can be misleading

Steps to reproduce

1. gz sim -v 4 shapes.sdf
2. Add any gui plugin and see an error msg printed

Output

Adding the ApplyForceTorque gui plugin prints out:
