Remove ARP matching for single ARP change, and consider publisher+name for matching

[florelis]

• For ARP matching we had a rule that would consider something a match if it was the only ARP change, but that is likely to give us false matches. This change removes that rule.
• For the string matching confidence algorithm, we would only consider matching package name with ARP name, and package publisher with ARP publisher, but sometimes the publisher would be included in the name and that would decrease confidence. For example, for package name = "Microsoft PowerToys" and ARP name = "PowerToys". This change makes the string matching also consider the string publisher+name.
• Also made the matching requirements for the unit tests stricter

I would really like false positives to be at 0. If the current algorithm is not at 0 in these unit tests, we should reconsider.

I'll send another PR once I figure out how to reduce the false positives.

One of the tests for winget list was expecting the output to contain the product code, but now that we can match it the output has the Id :)
