clean up and more (#2756)

# Description of Changes

This PR introduces multiple updates across various files and workflows:

### **What was changed:**
1. **Deleted Scripts:**
- `check_duplicates.py`: Removed script that checked for duplicate keys
in properties files.
- `check_tabulator.py`: Removed script that ensured no tabulators
existed in HTML, CSS, or JS files.

2. **Updated GitHub Actions Workflow (`pre_commit.yml`):**
- Added a weekly schedule trigger (`cron`) for the pre-commit workflow.
- Updated the `create-pull-request` action to exclude certain files
(`.github/workflows/.*`) from formatting.
- Improved detection and handling of staged changes during commit
creation.

3. **`.pre-commit-config.yaml`:**
- Adjusted regex for file matching in `ruff` and `codespell` hooks to
ensure better file filtering.
   - Removed local hooks that relied on deleted scripts.

4. **Scripts (`counter_translation.py`):**
- Updated file writing methods to enforce consistent newline characters
(`newline="\n"`).

### **Why the change was made:**
- To simplify the repository by removing unnecessary or outdated scripts
(`check_duplicates.py` and `check_tabulator.py`).
- To enhance the workflow automation by introducing a scheduled run for
pre-commit checks.
- To improve code formatting and file consistency by addressing newline
character issues and refining file exclusions in `pre-commit`.

### **Challenges encountered:**
- Ensuring that all references to deleted scripts were properly removed
from configuration files.
- Verifying that workflow and pre-commit changes do not introduce
regressions in existing automation.

Closes # (issue_number)
