* Updates the PR template to allow cleaner PR description workflow. * Cleans up some of the language/descriptions in check items. When a single commit PR is opened, GitHub will insert the commit message to the top of the PR template. Users who follow this flow previously needed to move this text to the bottom of the PR text, and remove the placeholder text. It's such common practice for github contributors to enter descriptions in PRs, we can omit the `Description` placeholder and be less prescriptive about where the description exists.
