I think the following places will need changing:

• https://github.com/microsoft/vscode-docker/blob/main/src/tasks/DockerBuildTaskProvider.ts#L93
• https://github.com/microsoft/vscode-docker/blob/main/src/tasks/DockerRunTaskProvider.ts#L85
• https://github.com/microsoft/vscode-docker/blob/main/src/docker/Contexts.ts#L38
• https://github.com/microsoft/vscode-docker/blob/main/src/commands/registries/logInToDockerCli.ts#L42
• https://github.com/microsoft/vscode-docker/blob/main/src/debugging/netcore/NetCoreDebugHelper.ts#L122
• https://github.com/microsoft/vscode-docker/blob/main/src/debugging/netcore/NetCoreDebugHelper.ts#L167
• https://github.com/microsoft/vscode-docker/blob/main/src/debugging/netcore/NetCoreDebugHelper.ts#L299
• https://github.com/microsoft/vscode-docker/blob/main/src/debugging/netcore/NetCoreDebugHelper.ts#L309
• https://github.com/microsoft/vscode-docker/blob/main/src/docker/DockerodeApiClient/DockerodeApiClient.ts#L78

https://github.com/microsoft/vscode-docker/blob/main/resources/python/launcher.py#L17 ought to but it's Python code and probably can't reasonably be made to work.
