Migration being created for WebhookEndpoint.api_version

[garyj]

Describe the bug
After adding dj-stripe 2.9.0b0 to the project and running makemigrations, the command tries to create a migration in dj-stripe package.

To Reproduce

• Add 2.9.0b0 to the project poetry add dj-stripe@2.9.0b0
  • This will also install stripe version 11.1.1
• Run manage.py makemigrations
  • if in docker container the error will be something like PermissionError: [Errno 13] Permission denied: '/opt/pysetup/.venv/lib/python3.12/site-packages/djstripe/migrations/0014_alter_webhookendpoint_api_version.py'

Changing the permissions to allow the migration to be create will create the following

class Migration(migrations.Migration):

    dependencies = [
        ('djstripe', '0013_2_9'),
    ]

    operations = [
        migrations.AlterField(
            model_name='webhookendpoint',
            name='api_version',
            field=models.CharField(blank=True, default='2024-09-30.acacia', help_text='The API version events are rendered as for this webhook endpoint. Defaults to the configured Stripe API Version.', max_length=64),
        ),
    ]

I did not set STRIPE_API_VERSION not DEFAULT_STRIPE_API_VERSION in my apps settings.

The default was introduced in ddf4b5. Which calls STRIPE_API_VERSION code in settings.py which defaults to stripe.api_version when STRIPE_API_VERSION is not set in settings.py. Hence in my case that resulted in 2024-09-30.acacia.

Digging a bit further I can see that in this migration the version defaults to 2024-04-10. Which is contradictory to settings.py which sets the DEFAULT_STRIPE_API_VERSION to 2020-08-27

So basically to avoid this migration being created I can set STRIPE_API_VERSION = '2024-04-10' in my settings.py.

@jleclanche do the webhooks with djstripe 2.9.x also work with newer API-versions or should they still be set to "2020-08-27"?
