YAML is malformed

### Product

dotnet CLI (dotnet new)

### Describe The Bug

When using a template condition to control whether or not to bring a job within a GitHub Actions build, the template engine mangles the output into something unrecognizable. The issue only appears if we have a conditional block around the job and goes away when we remove it.

https://github.com/unoplatform/uno.templates/blob/6b31f9694792aa09db71bdf0b455725af4c8fab7/src/Uno.Templates/content/unoapp/GitHub/workflows/ci.yml#L37-L62

### To Reproduce

Steps: Using the Uno.Templates
1. `dotnet new install Uno.Templates`
2. `dotnet new unoapp -ci github -o GitHubTest1 -skip`

Running this results in the `.github/workflows/ci.yml` generating like this:
```yml
name: CI

on:
push:
branches:
- main
- release/**

pull_request:
types: [opened, synchronize, reopened]

#endif

```

### Visual Studio Version

n/a

### Additional context

I have additionally tried:

- Removing the comments `# Add MSBuild to the PATH: https://github.com/microsoft/setup-msbuild`
- Removing the `timeout-minutes: ${{ fromJSON(env.STEP_TIMEOUT_MINUTES) }}`
- Switching from 8.0.100-rc.2.23502.2 to 7.0.403
- Adding a custom operation entry in the template.json and changing the operators for the condition in the ci.yml

None of these seemed to make a difference
