[DRE-maint] Bug#969237: ruby-moneta: please switch away from netcat

[Chris Hofstaedtler]

Source: ruby-moneta
Version: 1.0.0-6

Dear Maintainer,

ruby-moneta Build-Depends on netcat. This is a transitional package
on netcat-openbsd, and the transitional package should go away
sooner than later, preferably in bullseye.

Please switch to netcat-openbsd, or ncat, or similar.

Thanks,
Chris
