[docs] pip.parse still mentions the defunct `entry_point`

[dougthor42]

entry_point was removed in v0.34.0 (#1987)

rules_python/CHANGELOG.md

Lines 1546 to 1547 in c91d9f0

	### Removed
	* (pip): Removes the `entrypoint` macro that was replaced by `py_console_script_binary` in 0.26.0.

But it's still mentioned in the docs:

rules_python/python/private/pypi/pip_repository.bzl

Lines 355 to 361 in c91d9f0

	name = "pip-compile",
	actual = entry_point(
	pkg = "pip-tools",
	script = "pip-compile",
	),
	)

Lines 370 to 373 in c91d9f0

	name = "flake8",
	actual = entry_point("flake8"),
	)

This was only for bzlmod at first, because we could move faster with it. But since WORKSPACE is going to go away soon, maybe we should use 2.0 as an excuse to cleanup.
