build(package.json): set JS heap to 3 GB for typescript compilation

[petermetz]

On a laptop with 16 GB RAM the default JS heap size is not enough anymore
to do a full typescript build of the project from scratch.

The size of the heap for NodeJS processes gets determined at runtime by
an algorithm that (most likely) depends on the total RAM in your computer:

For laptops with 16 GB RAM or less, the heap ends up being calculated to
an amount that is too low at this size of the project so we have to give
it a little nudge by specifying the parameter for heap size explicitly to
be 3 GB instead of the default.
