Strictly check that the plugin's custom locales are loaded - Githubissues

I encountered a failing test, while trying to add a GitHub Actions workflow for automated testing to this repository. https://github.com/hidakatsuya/redmine_message_customize/actions/runs/9343817907/job/25713963042

The reason the above test fails is that the path of the directory where GitHub Actions runs the workflow is /home/runner/work/redmine_message_customize. As a result, the customizable_plugin_message? method always returns true. https://github.com/farend/redmine_message_customize/blob/04df5293d3715745de8f48f322679f39626dce48/lib/message_customize/locale.rb#L47-L49

This pull request addresses and resolves this issue.

I have confirmed the followings:
