Fix formatting in the default template (#3950)

## Changes
Fix formatting in the default template. Previously, there was a diff:

```diff

 def main():
     # Process command-line arguments
-    parser = argparse.ArgumentParser(description="Databricks job with catalog and schema parameters")
+    parser = argparse.ArgumentParser(
+        description="Databricks job with catalog and schema parameters"
+    )
     parser.add_argument("--catalog", required=True)
     parser.add_argument("--schema", required=True)
     args = parser.parse_args()
```

The problem is in the default template and not specific to PyDABs.

## Why
The template should be pre-formatted so that after the project is
initialized, it's already in its final state.

## Tests
Updated acceptance tests to check formatting for all files that template
produces
