Create slim render package without prettier

[thena-seer]

Goals

1. Provide a version of @react-email/render with a smaller footprint.
2. Appeal to users who need to optimize build size.

Background

Build size is very important for some javascript development use cases. @react-email/components is somewhat heavy for what it does, largely due to its dependency on prettier. In a repository that is already using react, @react-email/components adds about 12 Mb of install size, with prettier taking up 7.6 Mb. Right now, users are forced to clone-and-own if they want to remove the impact of this optional functionality.

Proposal

The prettier functionality is only relevant inside of a small conditional:

if (options?.pretty) {
    return pretty(document);
  }

It would be extremely simple to provide a version of @react-email/render that does not contain this dependency. It could be a separate package, or a separate export inside of the same package.

I would be happy to help contribute.
