vdk-jupyter: add py-to-ts-interfaces to build (#1765)

What:
Added py-to-ts-interfaces to build. 

What the changes do:
- Instruct npm to download the py-to-ts-interfaces package from the main
branch of the repository located at
https://github.com/Syndallic/py-to-ts-interfaces
- build script by updating the "build:interfaces" script in the
package.json (the npx command is used to run the installed
py-to-ts-interfaces package)

Why: linked to the issue
#1690

Tests: tested manually the build by adding new options to VdkOptions in
the python project
