Can not use the new static search in PyDPF

[jorgepiloto]

In this pull-request on PyDPF, the CI/CD complains about:

 Handler <function create_search_index at 0x000001AA03F281F0> for event 'build-finished' threw an exception (exception: unsupported operand type(s) for /: 'str' and 'str')

This is strange because in:

ansys-sphinx-theme/src/ansys_sphinx_theme/search/fuse_search.py

Lines 129 to 152 in 201e4aa

	def create_search_index(app, exception):
	"""
	Generate search index at the end of the Sphinx build process.
	Parameters
	----------
	app : Sphinx
	Sphinx application instance.
	exception : Exception
	Exception raised during the build process, if any.
	"""
	if exception:
	return
	search_index_list = []
	for document in app.env.found_docs:
	search_index = SearchIndex(document, app)
	search_index.build_sections()
	search_index_list.extend(search_index.indices)
	search_index_path = app.builder.outdir / "_static" / "search.json"
	with search_index_path.open("w", encoding="utf-8") as index_file:
	json.dump(search_index_list, index_file, ensure_ascii=False, indent=4)

The object:

ansys-sphinx-theme/src/ansys_sphinx_theme/search/fuse_search.py

Line 150 in 201e4aa

search_index_path = app.builder.outdir / "_static" / "search.json"

Extends from the pathlib.Path object.
