Templates using `dotty` name need to be updated to `scala3`

[nicolasstucki]

We still have the dotty name in dotty-example-project, dotty.g8, dotty-cross.g8, dotty-staging.g8 and dotty-tasty-inspector.g8.

They should be named scala3-example-project, scala3.g8, scala3-cross.g8, scala3-staging.g8 and scala3-tasty-inspector.g8.

Not sure if we can rename the projects without breaking the previous links. If we can't rename we can just create copies with the new names.

You are welcome to also move them to the scala organization on GitHub, if you like.

"I don't have permission to create public repos on scala", so it won't allow me to move. FTTB I'll just rename those projects.

[anatoliykmetyuk]

Repos renamed. sbt new resolves old names correctly to the new names. Old links are also resolved correctly. I'll move them to scala upon the availability of permissions.

[SethTisue]

I sent you an invite to join https://github.com/orgs/scala/teams/admins/members , so I think that should give you the permissions you need?

[anatoliykmetyuk]

Accepted the invite, still the same error.

[nicolasstucki]

@anatoliykmetyuk did you rename those in the docs as well?

[SethTisue]

@anatoliykmetyuk I added you to https://github.com/orgs/scala/people?query=role%3Aowner. that should do it?

[nicolasstucki]

@anatoliykmetyuk you will also need to update Travis as it stoped running tests due to the name change

[anatoliykmetyuk]

It worked, thanks @SethTisue.
@nicolasstucki yep, need to do that all as well. I hope I'll find some time on Friday.
