Function create_last_migration_table 

pub async fn create_last_migration_table(
    tx: &mut Transaction,
    table_name: &str,
) -> Result<(), Error>

Creates the “last_migration_table” if it doesn’t exist already

This table is used to track which migrations have already been applied.

This would be its rorm shape:

#[derive(Model)
#[rorm(name = "<table_name>")]
struct LastMigrationTable {
    #[rorm(id)]
    id: i64,

    #[rorm(auto_update_time)]
    updated_at: OffsetDateTime,

    migration_id: i32,
}
