feat: deprecate and archive prebuilt bindings for opc provider (#266)

HashiCorp has made the decision to stop publishing new versions of
prebuilt Terraform `opc` provider bindings for
[CDK for Terraform](https://cdk.tf). Once this PR is merged, the
[cdktf/cdktf-provider-opc](https://github.com/cdktf/cdktf-provider-opc)
repository will be archived and will no longer
be supported in any way by HashiCorp. Previously-published versions of
the prebuilt `opc` provider will still continue
to be available on their respective package managers (e.g. npm, PyPi,
Maven, NuGet), but these will not be compatible with
new releases of `cdktf` and are no longer eligible for commercial
support.
