[MikeMcC399]

Situation

Unclear documentation for formatting version references leads to inconsistent formatting of some aspects of the CHANGELOG.md which is sourced into the published changelog website reference page.

Change

• Clarifies that major version numbers (e.g., 15) should not be wrapped in backticks
