Migration Add API Broken

In version 1.2.15 the Migration.Add API has breaking changes that make it no longer usable.

I have been using migrations in Go like so:

ms.Add(migrate.Migration{
		Name:    "20241024-initial-migration",
		Comment: "init first model",
		Up: func(ctx context.Context, db *bun.DB) error {
           ...
        },
        Down: func(ctx context.Context, db *bun.DB) error {
           ...
        },
})

Since https://github.com/uptrace/bun/commit/d92e29e459ae2804ad48e1b4f6a8147211a47a57 this is no longer possible due to a private type being used in the definition of the Up and Down members.

Is there a migration path (pun not intended) from Add to Register that won't break compatibility with migrations that have already been run?
