Allow blocked environment variables through if they're included explicitly in terminal launch configs

• VSCode Version: 1.47.1 (not insider as I can't get docker builds working on that for some reason)
• Local OS Version: Windows 10 2004
• Remote OS Version: WSL2 Ubuntu 20.04
• Remote Extension/Connection Type: Docker Desktop using WSL2 backend

Steps to Reproduce:

1. Create a new project with a single file:

# .devcontainer/devcontainer.json
{
  "image": "alpine:latest",
  "remoteEnv": {
    "GOOGLE_API_KEY": "api-key",
    "GOOGLE_SOMETHING_ELSE": "something-else"
  }
}

2. Rebuild and Reopen in Container
3. In the remote terminal, check the environment for variables:

$ printenv | grep GOOGLE

Expected outcome:

GOOGLE_API_KEY=api-key
GOOGLE_SOMETHING_ELSE=something-else

Actual outcome:

GOOGLE_SOMETHING_ELSE=something-else

This is the same no matter the base image used. Changing the name of GOOGLE_API_KEY to anything else, even by a single character, allows it through.
