Abide by hideSourceMaps option in nextjs webpack config

@andreiborza Is this not supported? I see it in the docs here: Link

The reason I found this thread is that we still get the reference to the map in our chunks even if the option is set.

@cupofjoakim Hi, thanks for writing in. Seems like we slightly dropped the ball on this one with v8. The option is indeed in the docs and also in the type definitions but it doesn't do anything.

What should happen though by default in the SDK is that the client chunks should not have a source mapping URL at the bottom unless you set productionBrowserSourceMaps to true.

We'll update the typedefs by deprecating them and update the docs but can you potentially either confirm that you are using productionBrowserSourceMaps or would you mind providing a reproduction example? Thanks!

Closing this in favor of this: #13993

If no explicit user-setting is provided, we will enable source maps generation by setting hidden.
