fix(ci): Exclude config/types.ts in @sentry/nextjs from circular dependency check (#4598)

The library we use to detect circular dependencies, `madge`, has a bug wherein local files whose names match node modules cause false positives. (For more details, see pahen/madge#306.) In our case, it was triggered by #4597, which added an export from  file (`config/types.ts`) which depends on the node module `webpack` and which is depended upon by the local file `config/webpack.ts`.

To solve this for the moment, this excludes the problematic file from the check.
