Fix pdoc rendering for ` save_image_in_format()`

[ehrenfeu]

This section renders nicely in VS Code:

python-imcflibs/src/imcflibs/imagej/misc.py

Lines 573 to 575 in b6e594b

	>>> save_image_with_extension(imp, "OME-TIFF", "/output/path", 1, 3, True)
	# resulting files: /output/path/C1/image_title_series_001.ome.tif
	# /output/path/C2/image_title_series_001.ome.tif

Unfortunately, that's not true for pdoc:
