MicroBuild Install Signing Plugin Task Fails on Alpine Due to Missing Python venv

[ellahathaway]

When the MicroBuild Install Signing Plugin task runs in Azdo pipelines, it installs multiple Python packages directly onto the machine, bypassing a virtual environment. Alpine Linux, however, mandates the use of a virtual environment for Python package installations. As a result, the task fails on Alpine due to this requirement not being met. This issue prevents enabling signing on environments that use Alpine, such as aspnetcore Linux musl builds.

@ellahathaway Did this ever get resolved?

[ellahathaway]

It did not. However, this issue has been circumvented by dotnet/aspnetcore#60260, which moved aspnetcore builds off of alpine and onto azure linux. Given that, I'll close this issue as a "won't fix."
