Make default_picking_policy a required field in settings
## Code Before:

from odoo import fields, models


class StockConfigSettings(models.TransientModel):
    _inherit = 'stock.config.settings'

    security_lead = fields.Float(related='company_id.security_lead')
    default_new_security_lead = fields.Boolean(string="Security Lead Time for Sales", default_model="stock.config.settings", help="Margin of error for dates promised to customers. Products will be scheduled for procurement and delivery that many days earlier than the actual promised date, to cope with unexpected delays in the supply chain.")
    default_picking_policy = fields.Selection([
        ('direct', 'Ship products as soon as available, with back orders'),
        ('one', 'Ship all products at once')
        ], "Shipping Management", default='direct', default_model="sale.order")

## Instruction:
Make default_picking_policy a required field in settings
## Code After:

from odoo import fields, models


class StockConfigSettings(models.TransientModel):
    _inherit = 'stock.config.settings'

    security_lead = fields.Float(related='company_id.security_lead')
    default_new_security_lead = fields.Boolean(string="Security Lead Time for Sales", default_model="stock.config.settings", help="Margin of error for dates promised to customers. Products will be scheduled for procurement and delivery that many days earlier than the actual promised date, to cope with unexpected delays in the supply chain.")
    default_picking_policy = fields.Selection([
        ('direct', 'Ship products as soon as available, with back orders'),
        ('one', 'Ship all products at once')
        ], "Shipping Management", default='direct', default_model="sale.order", required=True)
