Description

• Adds changelogger note to the PR template.

Addresses SFCC CI tickets:

NOTE I've added tags to this project so we conform to semantic versioning. This allowed me to update the links properly without breaking any comparisons to previous versions. I left the old tags for historical purposes, but they tag the same version.

Manual Testing Steps

1. Passing pre-commit run --all-files.
2. Passing changelogger manage check.
