Wrong type in ZITADEL provider

[buehler]

The type in the ZITADEL Provider (options) is wrong. The thing about the underlying openidconfiguration type (https://github.com/nextauthjs/next-auth/blob/main/packages/next-auth/src/providers/zitadel.ts#L28) is that you cannot use PKCE without using "any" to type your options.

Your own recommended way to use ZITADEL is "PKCE", which needs to be configured as such (example):

export const authOptions: NextAuthOptions = {
  providers: [
    {
      id: 'zitadel',
      name: 'zitadel',
      type: 'oauth',
      version: '2',
      wellKnown: process.env.ZITADEL_ISSUER,
      authorization: {
        params: {
          scope: 'openid email profile',
        },
      },
      idToken: true,
      checks: ['pkce', 'state'], <<< THIS allows PKCE
      client: {
        token_endpoint_auth_method: 'none', <<< THIS allows PKCE
      },
      // profile method and other stuff
      clientId: process.env.ZITADEL_CLIENT_ID,
      // the type REQUIRES "clientSecret". but while using PKCE, there is none.
    },
  ],
  // other config
  secret: process.env.NEXTAUTH_SECRET,
};

export default NextAuth(authOptions);

I'd encourage you to update the ZITADEL provider in NEXT since you promote PKCE as the standard to use.
