fix: PR status summary should remove Note: Objects have changed outside of Terraform

[krrrr38]

what

• Add PlanSuccess.DiffSummary which returns only diff summary.
• use it on the pr status updater

why

PlanSuccess.Summary returns outside diff message, too. In the PR plan status doesn't need that information.

tests

• I have tested my changes by github action unit test

references

• closes PR status summary should remove Note: Objects have changed outside of Terraform #3009

Thanks for the quick fix!

I noticed one more issue (feat request?). We summarize on plan but not on apply so it just results in Apply complete status instead of Applied 2 created, 3 changed, 4 destroyed. I wrote up #3041 in case anyone is interested.
