Try also removing the other case where --force is used

It was originally added by https://github.com/ruby/setup-ruby/pull/253,
in order to fix CI. However, now CI passes without it so I assume this
was fixed by rubyinstaller2.

Force actually bypasses dependency constraints so it's actually
installing the latest Bundler in a version of Ruby that's incompatible
with it.
