Allow check-modified-files-only to be used in combination with file-extension

[Andarist]

As far as I can tell this:

github-action-markdown-link-check/entrypoint.sh

Lines 109 to 117 in 820c058

	for i in "${FILE_ARRAY[@]}"
	do
	if [ ${i: -3} = ".md" ]; then
	FIND_CALL+=("${i}")
	COMMAND="${FIND_CALL[@]}"
	$COMMAND &>> error.txt || true
	unset 'FIND_CALL[${#FIND_CALL[@]}-1]'
	fi
	done

is ignoring file-extension option altogether.

I would prepare a PR adding this functionality, but unfortunately, bash scripting is not my strongest suit. If nobody picks it up I might come back to take a stab at implementing this but this might take some time before I get to it.
