Visual Studio Components template directive doesn't get rendered

[drewbrew]

Describe the bug
I tried to run briefcase build windows VisualStudio on a new Windows 11 box (Python 3.10) without VS installed and the error message didn't tell me which components I need.

To Reproduce
Steps to reproduce the behavior:

1. Do a clean Windows 11 installation
2. Install Python 3.10 from the Microsoft store
3. Open a command prompt
4. Run some commands:

cd \path\to\your\code
python3 -m pip install --upgrade --user pip setuptools wheel
python3 -m venv .venv
.\.venv\Scripts\activate
pip install briefcase
briefcase create windows VisualStudio
briefcase build windows VisualStudio

5. Receive this error message:

(.venv) C:\Users\winst\code\briefcase-windows-VisualStudio-template\tests\apps\verify-pyside2>briefcase build windows VisualStudio

Visual Studio does not appear to be installed. Visual Studio 2022 Community
Edition can be obtained as a free download from:

    https://visualstudio.microsoft.com/vs/community/

When you install Visual Studio, ensure you install the following workloads
and additional components:
{VSCODE_REQUIRED_COMPONENTS}
If you have Visual Studio installed in a non-default location, you must
either put MSBuild.exe in your path, or define an MSBUILD environment
variable that points at the MSBuild.exe provided by your Visual Studio
installation.

Expected behavior
{VSCODE_REQUIRED_COMPONENTS} gets rendered into a list of components I should install.
