This is because the tests expect to install dlv@latest, but for go1.19 or go1.20, the extension pins the compatible dlv version https://github.com/golang/vscode-go/blob/61901bbc6123dd9c4eb7ac9195886635968763e0/extension/src/goTools.ts#L76-L78 and they do not exist in the fake local proxy.

The fix is non-trivial and cannot be done before v0.42.0. Since this is a bug in the fake proxy arrangement and the test failure actually indicates the dlv installation with go1.19 or 1.20 pick the intended pinned versions.
