gh-93096: Remove run block in heapq

[donbarbos]

we can use next command for doctests: ./python -m doctest Lib/heapq.py -v

and we already loading doctest in next line:

cpython/Lib/test/test_heapq.py

Lines 30 to 45 in ebc24d5

	defload_tests(loader, tests, ignore):
	# The 'merge' function has examples in its docstring which we should test
	# with 'doctest'.
	#
	# However, doctest can't easily find all docstrings in the module (loading
	# it through import_fresh_module seems to confuse it), so we specifically
	# create a finder which returns the doctests from the merge method.
	classHeapqMergeDocTestFinder:
	deffind(self, *args, **kwargs):
	dtf=doctest.DocTestFinder()
	returndtf.find(py_heapq.merge)
	tests.addTests(doctest.DocTestSuite(py_heapq,
	test_finder=HeapqMergeDocTestFinder()))
	returntests

I don't think this addresses any known or real user problem. It just makes life more difficult for the module maintainer.

This looks like redundant code. And we already have more general way to run doctest (via python -m doctest)
