Fix requirement for python3.12 (#16215)

* Fix pip version constraint for Python 3.12 compatibility

Remove outdated pip<22.0 constraint that was a workaround for
pip-tools#1558. This issue was fixed in pip-tools 6.5.0+ and
the old constraint breaks Python 3.12 where pkgutil.ImpImporter
was removed.

* Update requirements.txt

* Fix license file inconsistencies with requirements

- Rename awx-plugins.interfaces.txt to awx-plugins-interfaces.txt
  to match the package name in requirements
- Remove backports-tarfile.txt and importlib-resources.txt as these
  packages are no longer in requirements

* Fix updater.sh for pip 25.3 normalized output format

Changes to requirements_git.txt:
- Update to PEP 440 format (name @ git+url) to match pip-compile output
- Normalize package names (hyphens instead of dots/underscores)
- Sort extras alphabetically with hyphens (e.g., jwt-consumer not jwt_consumer)
- Add documentation explaining format requirements

Changes to updater.sh:
- Escape BRE regex metacharacters in sed pattern to handle brackets in extras
- Change sed delimiter from ! to | to avoid conflict with comment text
- Add explicit return statements to functions
- Assign positional parameters to local variables
- Redirect error messages to stderr
- Replace backticks with $() for command substitution
- Pin pip to version 25.3

requirements.txt regenerated via updater.sh

* Normalize package names in requirements.in to match pip output

- prometheus_client -> prometheus-client
- setuptools_scm -> setuptools-scm
- dispatcherd[pg_notify] -> dispatcherd[pg-notify]

PEP 503 specifies that package names should use hyphens.

* Fix license files to match normalized package names

- Remove awx_plugins.interfaces.txt (duplicate of awx-plugins-interfaces.txt)
- Rename system-certifi.txt to certifi.txt to match package name
