ci: remove libraries from compile-examples.yml workflow

[aliphys]

This PR removes the explicit mention of the libraries in the workflow file.

Arduino_UnifiedStorage/.github/workflows/compile-examples.yml

Lines 69 to 71 in 7739373

	- name: Arduino_USBHostMbed5
	- name: Arduino_POSIXStorage
	- name: ArduinoRS485

Following #29 and this PR all three dependancies are listed inside the library.properties file.

Although the dependancies are listed in the library.properties file they do not seem to be loaded by the runner: https://github.com/arduino-libraries/Arduino_UnifiedStorage/actions/runs/6906243043/job/18790834190#step:3:211

@per1234 Can you share your thoughts on this?

[per1234]

The arduino/compile-sketches action does not automatically install the libraries listed in the depends field of library.properties. So you must explicitly specify the library dependencies that should be installed in the GitHub Actions workflow, as was done previously.

There is no such capability by default because the action does not install the Arduino_UnifiedStorage library via Library Manager. Instead, it is being manually installed from the checked out repository.

The addition of such a capability, where the action parses the library.properties file and then automatically installs the libraries found there, has been proposed but the feature was not implemented so far.

@aliphys Any update on this?

@sebromero This fix is dependant upon arduino/compile-sketches#205 being merged.
