Improvements to Telemetry Extractor Build

[lramos15]

Changes as discussed in #76029 and #76113.
I currently have just hardcoded the commit id into the scripts to allow reproducibility until we release an NPM package as I was advised by @sbatten and @Tyriar that it wouldn't be worth the effort to implement something similar to Distro's commit checkout process.

@lramos15 Good job!

I've pushed the following changes before merging this in:

• Extractor module
  • Add typescript as a dev dependency
  • Add tsc as a postinstall script
  • Make the created JSON objects be compact instead of formatted with 4 spaces indentation
• Build
  • Clone the tool repo to a better place: $BUILD_STAGINGDIRECTORY
  • Move the built files to a better place: .build/telemetry
