DINAR-PORT: update python to 3.10

Here is the error I'm trying to fix:

```
  File "/home/runner/work/access-addons/access-addons/odoo-module-migrator/odoo_module_migrate/migration_scripts/migrate_160_170.py", line 35, in AbstractVisitor
    def add_change(self, old_node: ast.AST, new_node: ast.AST | str):
TypeError: unsupported operand type(s) for |: 'type' and 'type'
```
