What does this PR do?

This PR makes an updated on the SearchRequest. java file where another contributor tracked for a period of time and found the SearchRequest.toString() problem:
When String [] is used as key and value, it will not be serialized, so according with the recommendations this code would solve the problem before serializing to httpRequest.

HI @ancatoza,
Thank you for this PR! I advise you to read the CONTRIBUTING file, try to build the project and also to pass the linter with this command line:

./gradlew spotlessApply

The code seems great but you will need to add a test for this new method getStrArrays in src/test/java/com/meilisearch/sdk/SearchRequestTest.java and also one to check if the bug from the issue it still present

Hi @alallema and @ancatoza as stated here #573 (comment)

There is no real evidence of this issue, and in fact, we do have test coverage for that specific use case. So, until we don't have a reproducible use case in our tests or outside of it, like the repo I suggested in the linked comment, I don't see the point of keeping this PR open!

I appreciate the effort @ancatoza feel free to keep contributing!
