#35854: Order of "choices" on CharField randomly changing forcing new migrations
despite no changes.

I have a field `attachment_type` in a class that uses
{{{
TYPE_CHOICES = {
("image", "Image"),
("document", "Document"),
("audio", "Audio"),
("video", "Video"),
}
}}}
Every `makemigrations` call generates a new migration for that field:
{{{
migrations.AlterField(
model_name="genericattachment",
name="attachment_type",
field=models.CharField(
choices=[
("audio", "Audio"),
("document", "Document"),
("video", "Video"),
("image", "Image"),
],
default="image",
max_length=10,
),
),
}}}
I noticed that the order of the choices in the migration changes every
time. It doesn't seem to have a consistent method to compare the set of
tuples properly and so it generates a new migration every time. I have not
yet observed that it even accidentally collides in a way that does not
generate a new one.
