support dependencies = (...)

Description

currently I have migrations like this:

# Generated by Django 4.2.17 on 2024-12-10 17:46
"""Add display_order field to Story model."""

from django.db import migrations, models


class Migration(migrations.Migration):
    """Migrations."""

    dependencies = (
        ("core", "0001_initial"),
    )

    operations = (
        migrations.AddField(
            model_name="story",
            name="display_order",
            field=models.PositiveIntegerField(
                default=0,
                help_text="Order of the story in the frontend display.",
            ),
        ),
    )

they use tuples for dependencies and operations to make mypy and ruff happy. django-stubs defines Migration.dependencies as an instance sequence, and ruff only allows mutable ClassVars to be defined as a class variable

rebase_migration fails to process these sorts of migration:

$ python manage.py rebase_migration core
CommandError: Could not find dependencies = [...] in '0005_story_display_order.py'
