Allow test sketches to be outside examples folder

Thanks for your suggestion, but the current configuration of the rule is as intended. If you want to add test sketches to the library, please put them under the extras folder as suggested by the rule message.

There is a proposal for adding a dedicated folder for test files to the Arduino Library Specification:

arduino/arduino-cli#990

However, the rule would only be adjusted if that proposal was accepted.
