Devcontainer not working

[Vynce]

Describe the bug
I tried to follow https://rss-bridge.github.io/rss-bridge/For_Developers/Github_Codespaces_Tutorial.html to get a devcontainer up and running. The container image fails to build with the error pecl: not found. It fails the same way with Codespaces and running the devcontainer locally.

Desktop:

• OS: macOS 15.1.1

Additional context
I tried modifying .devcontainer/Dockerfile to install make php-dev php-pear. That gets further, but then it fails with docker-php-ext-enable: not found. docker-php-ext-enable appears to be a script that's only included with the official php docker base images, but this docker image is using debian:12-slim. I'm not familiar enough with php development to know how to proceed at this point.

I'm aware but unable to fix it. See #4223

I've been trying to get @VerifiedJoseph to chip in because he was working php dev containers in his projects but he's been silent :)
