Replace `tsc` with `rollup-plugin-dts` in build

[amannn]

Is your feature request related to a problem? Please describe.

We're currently using tsc to generate type definitions. This unfortunately drags in types from externals. We should investigate how we can switch to rollup-plugin-dts to correctly mark external types as such.

Describe the solution you'd like

Switch to rollup-plugin-dts or investigate if externals can be handled correctly with tsc.

Describe alternatives you've considered

I'm not aware of any externals config to be used with tsc.

Are you sure this can be fixed with build changes as described?

When I look into built definition files, I see:

// next-intl/dist/types/navigation/shared/BaseLink.d.ts
import { type LinkProps } from 'next/link.js';
import { type ComponentProps } from 'react';
import { type Locale } from 'use-intl';
import type { InitializedLocaleCookieConfig } from '../../routing/config.js';
type NextLinkProps = Omit<ComponentProps<'a'>, keyof LinkProps> & Omit<LinkProps, 'locale'>;
type Props = NextLinkProps & {
    locale?: Locale;
    localeCookie: InitializedLocaleCookieConfig;
};
declare const _default: import("react").ForwardRefExoticComponent<Omit<Props, "ref"> & import("react").RefAttributes<HTMLAnchorElement>>;
export default _default;

By "drags in types from externals", do you mean importing React? If so, for me it looks alright - that's the same way Next exports its Link types. I.e. doesn't seem like there's any problem with the dts files.

// next/dist/client/link.d.ts
import React from 'react';

...

declare const Link: React.ForwardRefExoticComponent<Omit<React.AnchorHTMLAttributes<HTMLAnchorElement>, keyof LinkProps<any>> & LinkProps<any> & {
    children?: React.ReactNode | undefined;
} & React.RefAttributes<HTMLAnchorElement>>;
export declare const useLinkStatus: () => {
    pending: boolean;
};
export default Link;

IMO, in this case correct solution would be making sure React types stay updated. Dependabot can be configured to create PRs for that.
