[🐛 Bug]: [Ruby] Selenium manger in offline mode emits a warning

[MatzFan]

Description

This is a duplicate/reopening of #13809 but for the Ruby bindings - i.e. the log message "Exception managing firefox: Unable to discover proper geckodriver version in offline mode" is still set at [WARN], not [DEBUG] level when SE_OFFLINE is "true".

Reproducible Code

# with env var SE_OFFLINE set to "true"

require 'selenium-webdriver'

driver = Selenium::WebDriver.for :firefox
driver.quit

Debugging Logs

In my terminal output I see the following:

INFO Selenium [:logger_info] Details on how to use and modify Selenium logger:
  https://selenium.dev/documentation/webdriver/troubleshooting/logging

WARN Selenium [:selenium_manager] Exception managing firefox: Unable to discover proper geckodriver version in offline mode

The second message should be DEBUG level. Also, the first message does not appear when SE_OFFLINE is not set to true, so I expect that should not be there either.

@MatzFan, thank you for creating this issue. We will troubleshoot it as soon as we can.

I am unable to reproduce this issue. I see a DEBUG log in Selenium Manager, not WARN:

> set SE_OFFLINE=true

What Selenium version are you using, @MatzFan?

[MatzFan]

Hi, sorry I should have included that. 4.34.0 when reported, still occurs with 4.35.0 now.

Edit: My OS is Mint 22.1

@MatzFan I have just committed a patch to change the log level of that trace to DEBUG when offline mode is on. It will available for the next release of Selenium/Selenium Manager.
