Unexpected Behavior: Debug Logs returning `false` when `default_level = :info`

Environment

Ruby Version: 3.2.2
Semantic logger version: 4.16
Application/framework names and versions: Rails 6.1.7.4, Puma: 5.6.9
Rails Semantic Logger Version: 4.17.0.
Solidus e-commerce platform

Description

I encountered an issue while using rails_semantic_logger in a Rails project with the Solidus framework. When SemanticLogger.default_level = :info or config.log_level = :info is set, debug-level logs return false, which leads to unexpected behavior.

Here’s a simplified example of the issue:

order = Spree::Order.first
order.logger.debug "Testing" # This output `false` while the original behavior is to return `true` even if log level is set to :info

This behavior affects the Solidus gem's state_machine logic, where debug logs are used in transition callbacks. For example:

after_transition do |order, transition|
  order.logger.debug "Order #{order.number} transitioned from #{transition.from} to #{transition.to} via #{transition.event}"
end

You can see this code in context here

When logs are set to :info, the state_machine process fails silently.

Context

This logic is part of the Solidus framework, and no issues related to this behavior have been reported in their repository.
The problem arises because when log_level is set to info, logger.debug returns false

Expected Behavior

Even when default_level or config.log_level is set to :info, calls to logger.debug should return true as it happens with the original ActiveSupport::Logger
