Delete downloaded archive after extracting it during install

[darktohka]

Description:

During a Python / Pypy / GraalPy installation, after the downloaded archive is extracted, it is not deleted. This leads to the archive taking up disk space, and often mistakenly getting archived together with the Python version.

This pull request ensures the downloaded archives are deleted after they are extracted and no longer needed.
