[BUG] Incorrect changelog link

**Describe the bug**

Incorrect changelog link

**To Reproduce**
Steps to reproduce the behavior:
1. Go to `https://emberjs.com/releases/release/`
2. Click on `changelog` at "Read the [changelog](https://github.com/emberjs/ember.js/blob/v7.0.0/CHANGELOG.md) for Ember 7.0.0."
4. See error

**Expected behavior**

Looks like link should be https://github.com/emberjs/ember.js/blob/v7.0.0-ember-source/CHANGELOG.md
instead of https://github.com/emberjs/ember.js/blob/v7.0.0/CHANGELOG.md

**Additional context**
I guess it comes from https://github.com/ember-learn/ember-website/blob/9b8519d81724c1ece58e29e6557c64996ce884a6/data/project/ember/release.md?plain=1#L8

but for install `7.0.0` is valid, not for tag to use in link (as there is no such tag)
