chore(node): update Node.js version in Dockerfile and config.json

[yhabib]

Motivation

We have a version mismatch of Node between our dockerfile and config.json. Node 16 has not been supported for some time. This PR updates both the Dockerfile and config to the same version we use for development.

Additionally, we could upgrade to the latest patch, which addresses some security vulnerabilities (v18.20.6) but this is not done in this PR.

Note: Version 18.20 addressed a "breaking change" introduced in v18 regarding how Date manages the space between the time and AM/PM. This adjustment was made following the update to the standard.

In many formatting patterns, ASCII spaces are replaced with Unicode spaces (e.g., a "thin space").

Changes

• Bump version of node in dockerfile and config.json to 18.20.5
