Update dependencies to use Go 1.21 and use TF SDK v2

[brucedewald]

NOTE: Before this PR can be merged vinyldns/go-vinyldns#94 must be merged and a new version of go-vinydns released to update in go.mod in this PR. I will keep this in a draft until that happens and then update this PR.

This PR does the following:

• Updating to use go 1.21 from 1.17 which was EOL'd in Aug 2022
• Upgrading to Terraform SDKv2 as SDKv1 was EOL'd in July 2021
  • Required updating some tests as v2 does not use hashes, but rather indexes for stored attributes
  • hashcode function is deprecated in SDKv2 so included it
  • other minor changes due to v2 differences
• Modified Makefile to more closely resemble go-vinyldns Makefile for consistency in Go projects

The goal of this PR is to have no functional changes, but just update it to current packages so that future PRs to add features are less cluttered & easier to review. As well, the goal was to update from older packages that have vulnerabilities
