Pytest folder naming update (#1437)

* Add utility functions for generating unique test case identifiers in pytest

- Introduced `get_pytest_case_id` and `get_pytest_baseline_name` functions in `conftest.py` to create unique identifiers for parametrized test cases and baseline files.
- Updated multiple test files to utilize these functions for generating output directory names, ensuring consistency and avoiding collisions in test outputs.
- Refactored test function signatures to include the `request` parameter where necessary for accessing the pytest request context.

* pre-commit fixes

* Refactor pytest utility functions for unique test case identifiers

- Introduced `_sanitize_test_id` function to handle sanitization of test identifiers for file paths.
- Updated test files to utilize the new `get_pytest_case_id` function for generating baseline file names, ensuring uniformity in output directory naming.
- Removed obsolete baseline files and added new ones to reflect updated test cases.

* Uniform test root path (#1435) it is actually overridden by my contribution

* pre-commit fixes

* Refactor test case identifier handling in pytest

- Replaced the `get_pytest_case_id` function with a new fixture `test_case_id` to streamline the generation of unique identifiers for test cases.
- Updated multiple test files to utilize the new `test_case_id` fixture, ensuring consistent output directory naming across tests.
- Removed obsolete references to the old identifier function.

* Refactor test function signatures to use `test_case_id`

- Updated the `garnet_models` and `garnet_stack_models` fixtures to replace the `request` parameter with `test_case_id` f

* Refactor pytest fixtures and update baseline files

- Changed the `scope` of some pytest fixtures from 'module' to default.
- Updated the `_sanitize_test_id` function to remove the prefix 'hls4ml/test/pytest/'.
- New mapping of old baselines json file to new naming style.

* Update CI template to include all tar.gz files in the pytest directory

- Modified the paths in the CI template to match all tar.gz files under the test/pytest directory instead of a specific pattern, required with the new naming convention.
