feat: Switch to govy for validation

[nieomylnieja]

Motivation

Code previously located at internal/validation is now being open-sourced. The new library govy comes with some initial changes to the structure of the code and the API.

Summary

Most of the changes were done via the following script, a few manual steps were required as well. I've also removed unnecessary type annotations while at it.

#! /usr/bin/env bash

old_import="github.com\/nobl9\/nobl9-go\/internal\/validation"
new_import="github.com\/nobl9\/govy\/pkg\/govy"

# List of functions to transfer from govy to rules package generated by:
# rg -N -I 'func.*govy\.Rule' -g '!*_test.go' | \
#   awk '/^func [A-Z]/ {sub(/[\[\(].*/, "", $2); print $2}'

while read -r file; do
  sed -r -i '

Release Notes

nobl9-go is switching to a brand new validation library, govy. The library was previously part of nobl9-go, but is now being open sourced! Go check it out ;)
