fix(cargo-lints): Don't always inherit workspace lints

When working on changes for #13805, I noticed that we always passed the contents of `[workspace.lints.cargo]` into the currently implemented lints,  even if `[lints]` was not specified or did not contain `workspace = true`. This PR makes it so we only pass in the workspace cargo lints if `[lints]` contains `workspace = true`.

You can verify this change by looking at the first commit, where I added a test showing the current behavior, and looking at the second commit and seeing the test output no longer shows a warning about specifying `im-a-teapot`.
