Remove @fbtjs/default-collection-transform as a peer dep from babel-plugin-fbt.

Summary

The default collection transform is an example, and does not need to be used directly. In my case, I have my own collection transform and it doesn't make sense for package manager to suggest installing the default collection transform in such cases. I suggest removing it as a peer dep.

mark it as optional instead? https://docs.npmjs.com/cli/v7/configuring-npm/package-json#peerdependenciesmeta

Actually neither might be a good idea since it is actually required in code when no custom transformer is specified:

fbt/packages/babel-plugin-fbt/src/bin/FbtCollector.js

Line 124 in 45ebf8c

const transform = require('@fbtjs/default-collection-transform');

I feel like it would be better to push this into the config where the collection transform is required to be specified via path or something. 🤷🏻‍♂️
