fix(logging): downgrade registration log from info to debug

[marevol]

Summary

Reduces log noise by changing the regex pattern registration success message from INFO to DEBUG level in PlaywrightClientCreator.

Changes Made

• Changed logger.isInfoEnabled() → logger.isDebugEnabled() and logger.info() → logger.debug() in PlaywrightClientCreator.java
• The registration success message is an internal detail that doesn't need to appear in production INFO logs

Testing

• Existing tests cover the registration logic; log level change doesn't affect functionality

Breaking Changes

• None

Additional Notes

• The message will still be visible when DEBUG logging is enabled
