fix meaninglessFileNames type in compiler options schema (#39698)

# Bug 

I would assume that this should be generated from TypeScript, but based on the [original PR](https://github.com/vercel/next.js/pull/38498/files) it wasn't clear that there was a way to generate these automatically.

Fixes the type of `styledComponents. topLevelImportPaths` and `styledComponents.meaninglessFileNames` so that it matches the [TypeScript type](https://github.com/vercel/next.js/blob/canary/packages/next/server/config-shared.ts#L457).

This was causing a warning here:

```
warn  - Invalid next.config.js options detected: 
  - The value at .compiler.styledComponents must be a boolean but it was an object.
  - The value at .compiler.styledComponents.meaninglessFileNames must be a boolean but it was an array.
  - The value at .compiler.styledComponents must match exactly one schema in oneOf.
 ```
