Help test Workspace Inheritance in preparation for stablization!

RFC 2906: Workspace inheritance allows sharing Cargo.toml settings across a workspace. Implementation is complete and we are looking for user reports on it to ensure it is ready to be stabilized, whether you do a throwaway port or are willing to depend on master and run with it for a period of time. For more information, see our testing instructions


Hi, I love the RFC a lot and hope to use it. I found that the well-known vscode plugin EvenBetterToml can't work well with the feature, so I add the support in the PR, and I guess it can help the feature to be used more widely.
