[sandbox] Update test/mkgrokdump/README

When regenerating v8heapconst.py, the v8 sandbox now has to be enabled
explicitly (using the v8_enabe_sandbox=true gn arg) as it is enabled by
default in Chromium builds, but not standalone v8 builds.

If you change the heap layout, expect this test to fail (in CQ). You will then
need to build x64 release and run `<outdir>/mkgrokdump > tools/v8heapconst.py`
to rebaseline.
