[repo] Post-release automation improvements

[CodeBlanch]

Changes

• When the GitHub Release is published at the end of the release process the automation will now perform two tasks:
  • Call the Core version update workflow on contrib
  • Post a final message on the prepare release PR announcing the packages are available on NuGet

Details

Test runs:

• [repo] Prepare release core-1.9.0-beta.1 CodeBlanchOrg/opentelemetry-dotnet#22 -> [repo] Core release 1.9.0-beta.1 updates CodeBlanchOrg/opentelemetry-dotnet-contrib#1

• [repo] Prepare release core-1.9.0 CodeBlanchOrg/opentelemetry-dotnet#23 -> [repo] Core release 1.9.0 updates CodeBlanchOrg/opentelemetry-dotnet-contrib#2

@CodeBlanch - Should we change this message? CodeBlanchOrg#23 (comment). make it explicit that more steps need to be followed for pushing to nuget?

This seems to look like there is no step in between the following two steps.

@vishweshbankwar Let me come back to this. I'm going to try to add more into the flow so you can do something like post "/PushPackages" in between those steps to automate that part too. I'll update the messages as part of that.
