convert_from_bytes has wrong argument name or docstring

[t-ae]

First argument of convert_from_bytes is pdf_file.

pdf2image/pdf2image/pdf2image.py

Line 277 in d415156

pdf_file: bytes,

Its docstring calls it pdf_bytes.

pdf2image/pdf2image/pdf2image.py

Line 302 in d415156

:param pdf_bytes: Bytes of the PDF that you want to convert

pdf_bytes sounds more accurate for me, but renaming can break compatibility.
