Support customer account API in hydrogen-codegen

[frandiox]

This PR only adds default values for Customer Account API in hydrogen-codegen just like we have for Storefront API.

Usage in codegen.ts:

import {pluckConfig, preset, getSchema} from '@shopify/hydrogen-codegen';

export default {
  overwrite: true,
  pluckConfig,
  generates: {
    ['storefrontapi.generated.d.ts']: {
       preset,
       schema: getSchema('storefront'),
       documents: [...],
     },
    ['customerapi.generated.d.ts']: {
       preset,
       schema: getSchema('customer'),
       documents: [...],
     },
  },
}

Personally I prefer explicit setting over options thats abstracted away. Curious just for my context where else we are using @shopify/hydrogen-codegen. So far I only found one usage in cli.

Also, dont forget changelog!

Other teams are using it for Admin API and other stuff.

Plus, it can be used by users directly if they want to add extra configuration for 3p APIs (e.g. a CMS). They can just have their own <root>/codegen.ts where they add codegen for other APIs, and import from @shopify/hydrogen-codegen to use ours.
That's why we currently rely on default values, because otherwise the user would need to pass kind of complex options to make the preset work for SFAPI (and now for CAAPI).

Thank you for the explanation @frandiox ! If possible, I think a README in the hydrogen-codegen package explaining to end user on how they can use this package would be really really helpful. 🙏

Yeah, pending task before we release v1 and write proper docs! For that, I'm waiting for dotansimha/graphql-code-generator#9709 to be released first so that we can stop patching depenendcies.

I guess we can add the example of this PR to the readme for now 🤔
