Expected behavior

hadolint permits the user to have a multi-line ENTRYPOINT or CMD, using exec form.

Actual behavior

hadolint raises DL3025 when the instruction is made to span multiple lines by escaping the newline.

Steps to reproduce the behavior

These do not raise an error, and are well-formed (that is, no issue here):

CMD [ "/bin/sh", "-c", "true;"]

CMD ["/bin/sh", "-c", \
  "true;"]

These do raise DL3025, but I think they are well-formed:

CMD ["/bin/sh", "-c", \
  "true; \
  true;"]

CMD ["/bin/sh", "-c", \
  "true && \
  true"]

These statements raise DL3025, but also are ill-formed for unrelated reasons:

CMD ["/bin/sh", "-c", \
  ]

Output of hadolint --version or
docker run --rm hadolint/hadolint hadolint --version or
docker run --rm ghcr.io/hadolint/hadolint hadolint --version:

(what I have installed is hadolint-bin 2.8.0-1 from the AUR.)

Thanks!
