Fix clean-build rule to handle .egg directories

[Copilot]

The clean-build Makefile target fails when encountering .egg directories because rm -f only handles files.

Changes

• Updated find . -name '*.egg' -exec rm -f {} + to use rm -rf for directory support
• Aligns with existing pattern used for *.egg-info cleanup

 clean-build: ## remove build artifacts
 	@echo cleaning build artifacts ...
 	rm -fr build/
 	rm -fr dist/
 	rm -fr .eggs/
 	find . -name '*.egg-info' -exec rm -fr {} +
-	find . -name '*.egg' -exec rm -f {} +
+	find . -name '*.egg' -exec rm -rf {} +

Original prompt

The unit test in pull request #21 is failing due to an error in the clean-build rule within the Makefile. The current command find . -name '*.egg' -exec rm -f {} + fails for directories, resulting in the error:

rm: cannot remove './venv/lib/python3.11/site-packages/pkg_resources/tests/data/my-test-package_unpacked-egg/my_test_package-1.0-py3.7.egg': Is a directory
make[1]: *** [Makefile:17: clean-build] Error 1
make: *** [Makefile:7: clean] Error 2

Solution:

Update the Makefile to ensure that the clean-build rule can handle both files and directories by replacing the rm -f command with rm -rf. The updated clean-build rule should look like this:

clean-build:
    find . -name '*.egg-info' -exec rm -fr {} +
    find . -name '*.egg' -exec rm -rf {} +
