fix(react-email): Make the userProjectLocation generic.

[julioflima]

To able to build locally and use NextJS just changing the root dir.

---

Summary by cubic

Made path handling in the React Email build generic so local Next.js builds work even if the project root changes. Preview server path now points to .react-email in the project root instead of a hard-coded build output.

• Bug Fixes
  • Set USER_PROJECT_LOCATION via path.resolve(__dirname, "../") instead of process.cwd.
  • Set PREVIEW_SERVER_LOCATION to path.join(userProjectLocation, ".react-email") instead of builtPreviewAppPath.

Pull Request Overview

This PR refactors the dynamic next.config.js generation in the build command to use proper Node.js path methods instead of string interpolation for path construction.

• Replaced hardcoded process.cwd() string interpolation with path.resolve(__dirname, "../") for determining the user project location
• Replaced hardcoded builtPreviewAppPath string interpolation with path.join(userProjectLocation, reactEmailDir) for the preview server location
• Introduced a reactEmailDir constant to avoid hardcoding the .react-email directory name

I'm not sure I follow, what's the reasoning for this? Doesn't it break existing flows?
