build: Fix Nx caching issue (#1935)

This does actually seem to resolve the caching issue.

There's a closed Nx issue about this
nrwl/nx#10442 and a merged PR
nrwl/nx#10455, however the PR was later reverted
nrwl/nx#10455 (comment) and does
not seem to have been fixed again yet as far as I can tell.

I've left a note on the original issue that I think it should be
re-opened.
