### NRediSearch
- Updated module so we're testing the right thing
- More output in the logging path for diagnosing issues
- Remove all the `FLUSHDB` calls masking issues
- Handle duplicate documents in latest module

Note: **locally** (on WSL 2), this fixes some issues and introduces stability but *does not* fix 2 scoring issues. Suggestions are coming back with scores > 1.0, which by the documentation is not supposed to happen...so I'm not sure what should be happening here. Here's the local WSL fail:
```
 NRediSearch.Test.ClientTests.ClientTest.TestGetSuggestionWithScore:
  Message: 
    StackExchange.Redis.RedisCommandException : Missing required fields:  score not within range: 2.11660146713257
  Stack Trace: 
    SuggestionBuilder.Build() line 99
    Client.GetSuggestionsWithPayloadAndScores(RedisResult[] results) line 1271
    Client.GetSuggestions(String prefix, SuggestionOptions options) line 796
    ClientTest.TestGetSuggestionWithScore() line 701
```
```
NRediSearch.Test.ClientTests.ClientTest.TestAddSuggestionGetSuggestionPayloadScores:
  Message: 
    StackExchange.Redis.RedisCommandException : Missing required fields:  score not within range: 2.71068739891052
  Stack Trace:

    ClientTest.TestAddSuggestionGetSuggestionPayloadScores() line 642
```

However, the current fixes tidy up the CI pipeline so I recommend merging this as-is, then I'll keep following up with various local errors and I'm looking at some Docker test options as alternatives to WSL2 so that people can run either.
