[docs] Add PR number to the release notes entry

[steveburnett]

Description

Update pull_request_template.md to recommend including the new PR number as part of the release note entry.

The Release Notes Guidelines have been edited to reflect this change.

Motivation and Context

Reviewing the release note entries as part of the release cycle and manually editing the individual release note entries to include the PR the entry is sourced from takes significant work as part of the release notes process. By asking the individual developer to include the PR number in their release notes entry, the release notes process should be quicker.

Impact

The pull request authoring process.

Test Plan

CI

After I merged this approved PR, I pushed a test branch and opened a new PR to production-test the update to the PR template.

It would be nice if we could have the release notes script do this automatically instead of relying on people to do this manually.

That would be nice! I can open an issue for the automatic solution, and this change to the template asking people to do so manually should help in the interim.
