fix: add missing dependencies and use require.resolve

[merceyz]

What's the problem this PR addresses?

Microbundle isn't working with Yarn PnP at the moment because it's trying to access dependencies it hasn't declared, and in one instance, not using require.resolve which causes babel to try to load presets from the root of the project.

How did you fix it?

• Moved @babel/preset-modules from devDependencies to dependencies
• Added missing dependency @babel/plugin-transform-regenerator
• Used require.resolve for environmentPreset
