Add sut alias record to repository rather than building it dynamically

[greg-1-anderson]

We don't need to dynamically generate these any more.

I should point out that this is using wildcard aliases, which means that we have a new feature. drush @sut.foo st is the same as drush --root=/path/to/sut --uri=foo st. Drupal won't find a foo directory, so it will select default. The database creds will be read from settings.php rather than taken from the alias. You can create foo via site:install.

If this is undesirable, we can explicitly list all of the environments rather than use the wildcard.

Is this a mistake? If not please add a comment. My path is different.

Also add link to wildcard aliases docs.

That's a mistake.
