Migrate from neotest-go to neotest-golang adapter with gotestsum runner

This commit performs a significant update to the Go testing adapter configuration by replacing the deprecated 'neotest-go' adapter with the newer 'fredrikaverpil/neotest-golang' adapter, which offers improved compatibility and features for modern Go development. The adapter key is changed from 'neotest-go' to 'neotest-golang' to match the updated plugin naming convention. The runner is switched from the basic 'go test' command to 'gotestsum', which provides enhanced test output formatting, parallel execution capabilities, and better integration with CI/CD systems through features like JUnit XML output and test result summarization. The previous experimental test_table configuration and custom args for test count, timeout, and verbosity are removed in favor of gotestsum's default, more robust handling of these aspects. This migration ensures that Go tests run with improved performance, better error reporting, and more reliable execution, particularly beneficial for large Go codebases and projects requiring comprehensive test reporting.
