Any idea why I need a babel.config.js file and a .babelrc?

Nobody has claimed this yet.

Using backpack in a monorepo with a common shared folder.

folder structure is like this:
````
project1/
.babelrc
project2/
.babelrc
shared
````

Both project1 and project2 have their own backpack config. I'm using babel's module-resolver plugin to resolve the shared folder so I can do stuff like `import db from 'shared/db'`.

All of this works fine but I get errors indicating babel isn't transpiling the code located in shared. Weirdly enough, copying the .babelrc contents to a babel.config.js fille work as intended.

Here is my .babelrc:

````

module.exports = {
presets: ['backpack-core/babel'],
plugins: [
'date-fns',
'@babel/plugin-proposal-nullish-coalescing-operator',
'@babel/plugin-proposal-optional-chaining',
[
'module-resolver',
{
root: ['./src'],
alias: {
shared: '../shared'
}
}
]
]
}
````

Any idea what i'm doing wrong here?

Compare the .babelrc files in project1 and project2 with the babel.config.js behavior, then inspect how Backpack resolves Babel configuration for code imported from shared. Reproduce the monorepo structure and module-resolver setup; done means the shared code is transpiled with a documented, consistent configuration.
