Disable npm lifecycle scripts and npx for security

[jespino]

Disable npm/yarn lifecycle scripts and npx in the devcontainer for security.

Changes

• Create .devcontainer/Dockerfile with security configurations
• Update .devcontainer/devcontainer.json to use the new Dockerfile

Security configurations

• npm config set ignore-scripts true - disables npm lifecycle scripts
• ignore-scripts true in .yarnrc - disables yarn lifecycle scripts
• Replace npx binary with error message stub

Fixes PDE-183

We could use $(which npx) to make this more reliable across repos

[jespino]

good point

I'm updating this here, and in other PRs

I tested, and it seems it does not work - it seems features are installed after the docker image which also makes sense if you think about it.
Which means we either:

• have to resort to "postCreateCommand"
• or develop our own feature :(
