Fix "Could not resolve org.jetbrains.kotlin:kotlin-test:1.9.23"

At this point, I don't know why we get this error.
Everything looks great and accessible in mvnrepository especially kotlin library.
But we do have the following error:
```
Could not resolve org.jetbrains.kotlin:kotlin-test:1.9.23.
     Required by:
         project :cosmotech-connector-api
      > Unable to find a variant of org.jetbrains.kotlin:kotlin-test:1.9.23 providing the requested capability org.jetbrains.kotlin:kotlin-test-framework-junit5:
```
Upgrading kotlin version to 1.9.25 will force the kotlin-test module's version to 1.9.25 too and it apparently fixes the compilation error message...
