pdoc3 doesn't use the latest version of the python file

[danleonte]

I used pdoc3 do document my python package https://github.com/danleonte/Ambit_Stochastics. In particular, i used to run

```pdoc3 --html ambit_stochastics````

or

```pdoc3 --html ambit_stochastics --force````

When I try to do it now, pdoc doesn't use the python files in the folder, but some older version of that. For example, the code in https://danleonte.github.io/Ambit_Stochastics/trawl.html, which can be viewed via the 'expand code button', is different from the one in the github repo. Further, the latex code doesn't render anymore. I uninstalled and reinstalled pdoc3 and it didn t help.

More interestingly, even after i removed one of the scripts, pdoc3 still generated documentation for that script.

We defer to importlib.import_module() to import referenced modules:

pdoc/pdoc/__init__.py

Lines 202 to 226 in 4aa70de

	@contextmanager
	def _module_path(module):
	from os.path import abspath, dirname, isfile, isdir, split
	path = '_pdoc_dummy_nonexistent'
	module_name = inspect.getmodulename(module)
	if isdir(module):
	path, module = split(abspath(module))
	elif isfile(module) and module_name:
	path, module = dirname(abspath(module)), module_name
	try:
	sys.path.insert(0, path)
	yield module
	finally:
	sys.path.remove(path)
	if isinstance(module, Module):
	module = module.obj
	if isinstance(module, str):
	with _module_path(module) as module_path:
	try:
	module = importlib.import_module(module_path)
	except Exception as e:
	raise ImportError(f'Error importing {module!r}: {e.__class__.__name__}: {e}')
	assert inspect.ismodule(module)

Maybe it prefers the pip-installed version of ambit_stochastics, if not the one in the current directory?
