allow modifiying admin-ui next.config.js

[shreyas-jadhav]

i want to modify headers() from next.config.js so that i can allow access to next-auth api routes from my front end app

@shreyas-jadhav can you elaborate on exactly what you're trying to do?
Maybe with an example?

The addition of the ability to configure the basePath was great! It would also be great to be able to modify the trailingSlash Next config option. For our use-case, we need to be able to set it to true. We're using an external system to route traffic to our Keystone App, and that system automatically adds trailing slashes. Without the ability to set trailingSlash to true, this results in endless redirects. Our only solution currently would be to downgrade to a much older version of Keystone so we could use the getAdditionalFiles workaround. When we downgrade to a version below 5.3.0, we then run into the issue of hanging builds.
