Describe the bug

When using the Go Companion extension, env variables aren't being loaded from the env file specified with the go.testEnvFile setting. If I disable the extension, things work as usual.

Steps to reproduce the behavior:

1. Add "go.testEnvFile": "${workspaceFolder}/.env" to your vscode settings
2. Create a .env file in the root of your workspace with a dummy env variable
3. Create a test that references the dummy env variable you created
4. Run the "Test: Run All Tests" command
5. See that the dummy env variable does not exist

I'm marking this as help wanted because I'm not sure when I'll get to it (the day job takes priority). It should be sufficient to add an entry to TestConfig and update TestRunner.#runPkg to check the config, read the file, and pass the vars to this.#spawn(...).
