fix: don't escape html tags inside of inline code in release notes

[mehalter]

This makes sure to only escape HTML tags that are not within inline code blocks as these are handled explicitly and not rendered the same way they are outside of code blocks.

Fixes #2366 🦕

Example, a commit such as the following:

feat: render all imagesets as <picture> `<picture>` `` `<picture>` ``

would render as the following markdown:

render all imagesets as <picture> <picture> `<picture>`

I updated the commits to follow the markdown syntax exactly for inline code including inline code blocks that contain ` characters. I also made sure all tests still pass along with adding a new test to fully validate the rest of the possible HTML escaping situations. This should be ready for review 🥳

Thanks so much for such a great project and I'm excited to be able to help contribute!
