Fix include directory

[AntoineGagne]

On OTP 26.0.2, the emulator calls fail with the following:

root@787c3fa7af3a:/app# erl -noshell -s init stop -eval "io:format(\"~s/erts-~s/include/\", [code:root_dir(), erlang:system_info(version)])."
Error! Failed to eval: io:format("~s/erts-~s/include/", [code:root_dir(), erlang:system_info(version)]).

Changing it to the version in the PR solves the issue:

root@787c3fa7af3a:/app# erl -noshell -eval "io:format(\"~s/erts-~s/include/\", [code:root_dir(), erlang:system_info(version)])." -s init stop; echo
/usr/local/lib/erlang/erts-14.0.2/include/
