Template Validation workflow fails on pull request.

[prasann]

Template validation workflow that runs as part of the pull_request fails at the create_comment step.

as per the github actions' readme: https://github.com/peter-evans/create-or-update-comment

Note: In public repositories this action does not work in pull_request workflows when triggered by forks. Any attempt will be met with the error, Resource not accessible by integration. This is due to token restrictions put in place by GitHub Actions. Private repositories can be configured to enable workflows from forks to run without restriction. See here for further explanation. Alternatively, use the pull_request_target event to comment on pull requests.

Likely, the PRs raised by non-maintainers will be triggered by forks I believe.

Example: https://github.com/Azure/Azure-DataFactory/actions/runs/4280602024/jobs/7452581479 - Failed job

Hello @prasann, thank you for reporting this and the fix. I have tried to use pull_request_target, but this event is run in the context of the base branch and doesn't contain the newest change, you can find the information here. So I choose to not comment when the pull_request is triggered by forks. But seems it doesn't work now. And I have fixed it today in this PR and this PR. And now I believe it will work as I expected.
