Need to support both 4.9 and 5.x.

While looking into the current esptool issue I came across with

pytest-embedded/pytest-embedded-serial-esp/pyproject.toml

Line 35 in a8466cb

"esptool~=4.9",

and I was just going to open a request here. But I see you already track this. Thank you!

This is a blocker for IDF-12564 which we plan to do in the next couple of weeks. Please let us know if we can be of any help to address this. Thanks! cc @radimkarnis @peterdragun
