Feature #2816 main_v6.0 enhance workflow dispatch testing (#2829)

* per #2816, update title of workflow displayed in Actions tab to display the repo that triggered the workflow on workflow_dispatch events. Preserve the behavior of pull_request and push events by displaying the PR title or head commit message respectively

* fix logic for run-name

* Update event info to note that the workflow was triggered manually if the repo/title was not provided. Update description of workflow_dispatch argument to describe what it can be used for when triggering manually. Only run step to build URL to commit that triggered workflow if it was triggered from an external repo

* add optional argument for workflow_dispatch to specify the title of the workflow run

* revert change to repository argument description since title argument was added to handle custom workflow run titles
