chore: add back env paths setting so cortex engine can load libraries properly

[louis-menlo]

This pull request includes changes to the extensions/inference-cortex-extension/src/node/index.ts file to enhance the setup and cleanup processes for the Cortex subprocess. The most important changes include adding a new function to set environment paths and updating the run function to utilize this new function.

Enhancements to subprocess setup:

• extensions/inference-cortex-extension/src/node/index.ts: Added a new function addEnvPaths(dest: string) to set the environment paths for the Cortex subprocess, ensuring the correct paths are added to PATH and LD_LIBRARY_PATH based on the operating system.

Updates to run function:

• extensions/inference-cortex-extension/src/node/index.ts: Modified the run function to call addEnvPaths(binPath) to set up the environment paths before executing the binary.
