Pre-fill credentials on admin panel onboarding

[brunobuddy]

It is hard to find the credentials in the page.

We could create an env variable (in .env) that tells the client that it has to suggest the default admin user in the login page fields

It is true on stackblitz demo but also on local install

@brunobuddy What about those who will create other accounts? Will they be prefilled with the admin credentials? It seems strange to me.

@SebConejo the seeder always create an admin@manifest.build user so every DB seeded in local/stackblitz/contribution will include the admin@manifest.build admin
