Fix/vendor node output

[SyedaAnshrahGillani]

This pull request addresses two minor but impactful issues in the project's vendoring scripts
(scripts/vendor-node.cjs and scripts/vendor-protoc.cjs), enhancing the robustness of the development
setup and improving the overall developer experience.

Changes Introduced:

1. scripts/vendor-node.cjs - Suppress node --version output:

   • Problem: Previously, the tryExecSync function used stdio: 'inherit' when checking the vendored
     Node.js version. This caused the node --version output to be printed to the console every time
     the bootstrap script ran this check, leading to unnecessary console noise.
   • Fix: Changed stdio: 'inherit' to stdio: 'pipe' in tryExecSync.
   • Benefit: This change prevents extraneous output, resulting in a cleaner and less verbose console
     during the bootstrap process. Developers will now only see relevant messages, improving clarity
     and focus.

2. scripts/vendor-protoc.cjs - Improve error handling and suppress protoc --version output:

   • Problem 1 (Error Handling): The main asynchronous function's error handler only logged errors
     but did not terminate the script with process.exit(1). If protoc vendoring failed, the bootstrap
     process would continue, potentially leading to confusing cascading errors later on.
   • Problem 2 (Console Noise): Similar to vendor-node.cjs, the tryExecSync function used stdio:
     'inherit' for the protoc --version check, adding unnecessary output to the console.
   • Fix 1: Added process.exit(1) to the error handler of the main async function.
   • Fix 2: Changed stdio: 'inherit' to stdio: 'pipe' in tryExecSync.
   • Benefit: The improved error handling ensures that the bootstrap process fails fast and provides
     immediate, clear feedback if protoc vendoring encounters an issue. This prevents wasted time
     debugging subsequent failures. The stdio: 'pipe' change also contributes to a cleaner console
     output, consistent with the vendor-node.cjs fix.

These changes are bug fixes that enhance the reliability and user-friendability of the project's
development setup, aligning with the project's contribution policy.
