Second PR to address https://github.com/coder/coder/issues/16230. See
the issue for more context and discussion.
It adds a "Continue with GitHub" button to the `/setup` page, so the
deployment's admin can sign up with it. It also removes the "Username"
and "Full Name" fields to make signing up with email faster. In the
email flow, the username is now auto-generated based on the email, and
full name is left empty.

There's a separate, follow up issue to visually align the `/setup` page
with the new design system: https://github.com/coder/coder/issues/16653
Using `go run` inside of a test is fragile, because it means we have to
wait for `go` to compile the binary while also constrained on resources
by the fact that Playwright and coderd are already running. We should
instead compile a coder binary for the current platform before the tests
and use it directly.
Closescoder/internal#168
Gets rid of the "global state" authentication, and adds a `login` helper
which should be called at the beginning of each test. This means that
not every test needs to authenticated as admin, and we can even have
tests that encompass multiple permission levels.
We also now create more than just the single admin user during setup, so
that we can have a set of users to pick from as appropriate.
