-  # 1. `bundle install` does not support auto-self-upgrade for pre-release bundler versions suffixed with ".dev"
-  # 2. ruby-head-wasm-wasi's component build depends on 2.6.0.dev, which added --target-rbconfig support
-  # 3. If the "bundle" command here is earlier than 2.6.0.dev, "bundle install" does *not* self-upgrade to
-  #    the specified pre-release version, and it overwrites the Gemfile.lock with the earlier command version.
-  # 4. Overwritten Gemfile.lock with the earlier bundler version causes auto-self-downgrade when running
-  #    "bundle install --target-rbconfig" inside "rbwasm build" command, then it fails because the earlier
-  #    bundler version does not support --target-rbconfig.
-  #
-  # Thus, we temporarily discard the Gemfile.lock changes here to prevent the auto-self-downgrade issue.

-  # a stable bundler version is released with --target-rbconfig support.
