The test suite has some YAML files that are used by test/unit/lib/redmine/configuration_test.rb. And the YAML files have a file extension ".yml.example" instead of the standard ".yml". This is to prevent "rake db:fixtures:load" from failing (#30811). Files with a “.yml” extension placed under “text/fixtures” directory are treated as test fixtures and cause the failure.

In Rails 6.1.4, db:fixtures:load now ignores YAML files under text/fixtures/files (see https://github.com/rails/rails/pull/42153). This means that "*.yml" files will no longer cause db:fixtures:load to fail if they are placed in that directory and we can stop using an awkward ".yml.example" extension.

The attached patch moves the YAML files under /text/fixtures/files directory and changes the file extension back to ".yml".
