fix(bazel): increase memory limit of ngc under bazel from 2 to 4 GB (#…

…31784)

This commit bumps the heap size of node/ngc under bazel to 4 GB instead of
the previous 2 GB. This brings it in sync with what the TS compiler uses
in g3, and fixes a bug where ngc would crash with OOM in worker mode.
