Upgrade GitHub workflows to use centralized global.json for .NET version (#735)

### Summary & motivation

- Replace all hardcoded `dotnet-version: 9.0.x` values in GitHub
workflows with a reference to the centralized `global.json` file for
consistent .NET versioning
- Reformat GitHub workflow files to use consistent indentation around
blank lines

This change fixes a sporadic error where the actions/setup-dotnet@v4
GitHub task sometimes installed an incorrect .NET version, causing
workflows to fail.

### Downstream projects

Update all GitHub workflow files to reference the `global.json` file
instead of hardcoded versions:

```diff
- dotnet-version: 9.0.x
+ global-json-file: application/global.json
```

### Checklist

- [x] I have added tests, or done manual regression tests
- [x] I have updated the documentation, if necessary
