Forward to v1.5.1

[bbasata]

Previously: #10

This PR updates this repo for parity with zclconf/go-cty v1.5.1. The changes remain "Unreleased" with no new release tag for the moment. This prevents a flood of Dependabot PRs like hashicorp/terraform-plugin-testing#444 for all affected providers.

Verification:

$ git ls-remote upstream refs/tags/v1.5.1^{}
