Dry run script does not work

[cs278]

Any attempt to use the dry run script (from the dev container) fails with the following error:

[dependabot-core-dev] ~ $ bin/dry-run.rb
/usr/local/lib/ruby/3.3.0/bundled_gems.rb:69:in `require': cannot load such file -- dependabot/javascript (LoadError)
	from /usr/local/lib/ruby/3.3.0/bundled_gems.rb:69:in `block (2 levels) in replace_require'
	from bin/dry-run.rb:114:in `<main>'

Reverting #11445 fixes the problem.
