python3-pydantic: upgrade 2.7.3 -> 2.8.2

* Set RECIPE_NO_UPDATE_REASON because of issues we have been having with
  getting out of sync with required python3-pydantic-core version
* Add RDEPENDS for ptest:
  - python3-pydoc (for test_help cases)
  - python3-email-validator
  - The standard library provides the getpass module, we provide it
    in the python3-unixadmin sub-package of python3 recipe.
  - python3-rich
