Dev Container Docker build failes if "from" keyword is used in a string in Dockerfile

• VSCode Version: 1.86.0
• Local OS Version: Ubuntu 22.04.3 LTS
• Remote OS Version: Ubuntu 22.04
• Remote Extension/Connection Type: Containers
• Remote Development Extension version: v.0.25.0

The "From" keyword is interpreted as a docker command if it is the first element in a new line even though it is part of a string.
The following example demonstrates the issue.

Minimal Example to reproduce the issue

1. Create files
   devcontainer.json

{    
    "dockerFile": "Dockerfile"
}

Dockerfile

FROM ubuntu:22.04

RUN echo ' Greetings \ 
from Simon' >> ~/test.txt

2. Reopen in container
3. Error:

 Error response from daemon: No such image: simon:latest
