Close #701, allow author to access the text of unexpected results in a portable way

[plocket]

In this PR, I have:

• [x] Added tests for any new features or bug fixes (if relevant)
• [x] Added my changes to the CHANGELOG.md at the top, under the "Unreleased" section
• [x] Ensured issues that this PR closes will be automatically closed

What do these changes do?

1. Give the user access to the artifact files and give them the paths to various reports so they can get those files and use them or their contents in whatever way they choose. For example, they can include the output in an issue. This includes paths to a new unexpected results[^1] file, but also other files .
2. Fix how we handle tag expressions that have multiple tags in them.
3. Add an actually failing test that we exclude and can test manually when needed.
4. See the changelog for more details.

[^1]: Note: Unexpected results means non-passing tests. For example, failures and undefined steps (typos).

Any manual testing I have done to ensure my PR is working

• Tested with error that wasn't from a cucumber test (which meant no artifacts existed at all). run: exit 55
• Tested with cucumber test error
• Tested with no errors

The workflow was able to create the "failure" issues correctly.
