Transfer the repository to github.com/ebitengine/ebitengine

This should be in a little far future.

Confirmed that transferring a repository should not be problematic.

I tested this with https://github.com/hajimehoshitest/gomoduletest. This was https://github.com/hajimehoshi/gomoduletest until v2, and moved to hajimehoshitest at v3. v2.0.2 was tagged after transferring, but go get github.com/hajimehoshi/gomoduletest/[email protected] succeeded.

So now we call this engine Ebitengine, we have to rename the package. We should be able to transfer to v3 in the following way smoothly:

Replace

import (
    "github.com/hajimehoshi/ebiten/v2"
)

with

import (
    ebiten "github.com/ebitengine/ebitengine/v3"
)

Of course, for a new project, we don't need the alias ebiten.
