remove libyaml-dev from BUILD_DEPENDENCIES

Because this is required on runtime
and BUILD_DEPENDENCIES will be removed at the end of installation
Installation of `libyaml-dev` is written in Dockerfile
so additional installation is not reeded

if not, following error reported on runtime

> LoadError: libyaml-0.so.2: cannot open shared object file: No such or directory - /usr/local/lib/ruby/3.2.0/x86_64-linux/psych.so

This is because Ruby 3.2.0 (psych 5.0.0) or later
does not contain libyaml any more
ruby/psych#541
