Describe the bug

I have a setup with two repositories, A and B, where Go code from B repo are symlinked into the A repo. Then the A repo are used as the workspace in vs code. When having the feature testOnSave enabled, then navigating to one of the symlinked files and then save it, the test tool are automatically run as expected, but fails with the following error:

Running tool: /usr/local/go/bin/go test github.com/marefr/symlink-go-test/a/pkg/extensions/something

no required module provides package github.com/marefr/symlink-go-test/a/pkg/extensions/something: go.mod file not found in current directory or any parent directory; see 'go help modules'

I expect the tests to run successfully since coping the command from the output, open a terminal, paste and run it works as expected.

Steps to reproduce the behavior:

See https://github.com/marefr/symlink-go-test for details, reproduction and detailed steps.
