[14.0][FIX] datamodel: replace deprecated use of "missing" argument

[davejames]

Deprecated use of "missing" argument leads to a warning in the Odoo logs when tests are run. This PR replaces "missing" with "load_default" as introduced in marshmallow-code/marshmallow#1742

[davejames]

pre-commit is failing because apispec is included in the external_dependencies in multiple places both with and without a version

I think it's outside the scope of this PR and I'm not sure what the best approach to deal with it is. I think the requirements.txt file is fine as it is

this is caused by #195 which should be rolled back because of this explanation acsone/setuptools-odoo#59

Feel free to revert it here.

seems legit

dismiss as build is not green yet

thanks @simahawk I've gone ahead and committed the auto-generated requirements.txt

[simahawk]

@davejames no big deal in this case but next time use git revert $hash 😉
