Dependencies between the latest fbt packages seems to be busted

🐛 Bug Report

It looks like that the most recent version of fbt, babel-plugin-fbt and babel-plugin-fbt-runtime

To Reproduce

Create an empty folder and get started with

npm i

Now that we got a fresh and empty module, let’s try to install fbt:

npm i fbt babel-plugin-fbt babel-plugin-fbt-runtime

We get the following error:

$ npm i fbt babel-plugin-fbt babel-plugin-fbt-runtime
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: undefined@undefined

npm ERR! Could not resolve dependency:

Note that babel-plugin-fbt and babel-plugin-fbt-runtime can be installed individually, but not together, fbt cannot be installed at all without using --force .

Expected behavior

Node install the fbt packages and we can continue out happy life.
