Add DotNetComponent

[ericstj]

The DotNetComponent type is used to report usage of the .NET SDK version

This is important as the .NET SDK will add redistributable content to the project, so using an older version may mean your application contains unserviced copies of the host or runtime. The TargetFramework and project type is reported as well since these influence what content the SDK may reference.

Some remaining work:

• Add documentation
• Support concurrency (protect cache)
• More tests - bad assembly, shared files under same global.json/root, ensure we halt global.json search appropriately.
• Answer question about PURL

PR Overview

This PR adds the DotNetComponent type and its corresponding detector along with tests and service configuration to enable detection of .NET SDK usage and project details. Key changes include:

• Introduction of DotNetComponent with properties for SDK version, target framework, and project type.
• Creation of DotNetComponentDetector to analyze project assets and global.json for .NET SDK version discovery.
• Addition of unit tests and configuration updates to wire up the new detector.

👋 Hi! It looks like you modified some files in the Detectors folder.
You may need to bump the detector versions if any of the following scenarios apply:

• The detector detects more or fewer components than before
• The detector generates different parent/child graph relationships than before
• The detector generates different devDependencies values than before

If none of the above scenarios apply, feel free to ignore this comment 🙂
