feat: DotnetWindowsInjector

[andrew-lozoya]

Description

This update introduces a DotnetWindowsInjector for injecting New Relic .NET instrumentation into Windows-based containers within Kubernetes. The injection includes support for both .NET Framework and .NET Core applications.

Key features:

• Automatically configures necessary environment variables for Windows .NET profiling and instrumentation paths.
• Ensures that the required Windows path volumes and nanoserver based init containers are properly set up for instrumentation files.
• Includes error handling to prevent duplicate environment variable settings if instrumentation is already configured.

Additionally, this PR adds a GitHub Actions workflow to automate the build and publication of Docker images for the instrumentation, targeting Windows Server 2019 and 2022. As well as updated chart helper functions.
