Fix #66

• :bug: Bug fix (non-breaking change which fixes a defect)

♻️ Anything particular you want feedback on?

@darrinholst can you please confirm that 1.1.0 works and that it really fixes #66? I wish I knew an automated way to fix this.

What I have in mind is something like cat some-rpc-file | cat node bin/cucumber-language-server.cjs --stdio and verify that we get some kind of OK response.
