Prior to this change, the failure analysis for an invalid configuration property value filtered out the configuration property sources property source. This property source contains a "duplicate" of all of the environment's other property sources but with configuration property support (such as relaxed/fuzzy matching of environment variables). This was done to prevent the reporting of duplicates when a property was found in both the configuration property sources property source and the "normal" property sources. An unwanted side-effect of this was that fuzzy matching of environment variables was lost so the origin of com.example.some-property would be found in the environment variable was COM_EXAMPLE_SOME_PROPERTY but would not be found if it was COM_EXAMPLE_SOMEPROPERTY. This commit addresses this side-effect by no longer filtering out the configuration property sources property source. To then prevent duplicates from being reported in the analysis, it instead deduplicates things based on the origin of each property that's found in the environment's property sources. Fixes gh-43380
