Changelog URL in PR template not pointing to the right place

The tiniest nitpick - the changelog link in the PR template actually points to https://github.com/iodide-project/iodide/CHANGELOG.md after PRs are submitted, e.g., #2130.

What I Did

What I Expected

The link should point at https://github.com/iodide-project/iodide/blob/master/CHANGELOG.md

What Happened

https://github.com/iodide-project/iodide/CHANGELOG.md which 404s

Thanks! For future reference, it is possible to submit PRs against these sorts of templates (see commit) -- feel free to do so in the future, no issue required. :)
