feat(nextjs): app router support

[subzero10]

Closes: #1070

Status

READY

Description

Adds support for the new App Router in Next.js.

Todos

• Implement support for app router
• Make sure that source maps are correctly uploaded for the app directory
• BONUS: support projects built with .tsx (Typescript) or .js files

[subzero10]

I also have an example project that I will push into the nextjs package with #1072.

Error reported automatically while rendering client-side component. Source maps applied successfully.

[subzero10]

Error reported automatically on the server side, during a data fetching method. However, most of the context is missing because Next.js does not propagate server errors to the Honeybadger React Error Boundary (since it's on the client side).

We can look into improving this with #1055.

@BethanyBerkowitz Can I please get another round of review 🙏 ?

Thanks!

This shows that the sourcemap was applied, but the file names are still minified... shouldn't they be the original file names and not minified ones?

Code looks good to me, I left minor questions / comments. Did you want me to test this in some way?

Are you referring to react-dom.production.min.js? This is a dependency, i.e. not part of the application code.
page.tsx is application code and appears to be shown correctly.

I don't think it's necessary at this point, but if you want to play with Next.js, feel free to do it!

@BethanyBerkowitz Can you please approve, if you are happy with my replies 😄 ?
