chore: update minimum supported node version to 10.13.0 (#7673)

Users cannot go through our current contribution guide and successfully install the repo due to the nock dependency, which now needs a minimum of Node 10.13.0.

Closes #7671

thanks for getting this started @winky! seems like you need to merge and update a couple of modules that were added recently.
