[docs][PATCH v2] ref-manual/tasks.rst: make do_clean description more explicit

From: anis <[email protected]>

The current do_clean task description is generic and does not
specify which files will be removed.

This commit adds details about the files that are removed by
explicitly listing the affected subdirectories.

+Running this task removes the working directory of the recipe (represented by its :term:`WORKDIR` value),
+the sstate manifests and the :ref:`stamps <overview-manual/concepts:Stamp Files and the Rerunning of Tasks>`.
+However, it does not remove the :ref:`sstate <overview-manual/concepts:shared state cache>`
+cache files. Consequently, if no changes have been made and the recipe is rebuilt
 after cleaning, output files are simply restored from the sstate cache.
 If you want to remove the sstate cache files for the recipe, you need to
 use the :ref:`ref-tasks-cleansstate` task instead
