ruby gem `spring` is required by command `bin/rails`, even in production environment

Please complete the following fields as applicable:

What version of the DMPRoadmap code are you running? (e.g. v2.2.0)

4.0.1

Expected behaviour:

In a production environment environment, gems from groups like development
are typically not installed, and should not be relied on. I even add the environment variable
EXECJS_RUNTIME=Disabled to ensure that rails does not try to compile assets or start
an asset compiler.

Actual behaviour:

If you have run bundle install with the following configuration ..

bundle config without test development ci

then the rails command fails with the following error:

$ bundle exec rails server
/usr/local/bundle/gems/bundler-2.4.8/lib/bundler/rubygems_integration.rb:280:in `block (2 levels) in replace_gem': spring is not part of the bundle. Add it to your Gemfile. (Gem::LoadError)
	from /opt/roadmap/bin/spring:14:in `<top (required)>'
	from bin/rails:7:in `load'
	from bin/rails:7:in `<main>'

If I removed the lines that try to load spring, then the command works again
