Fix JavaScript tests: update tests to pass config via parameter

[Copilot]

Three safe output handler tests (create_discussion.test.cjs, update_issue.test.cjs, close_issue.test.cjs) were failing after the JavaScript handler migration in #8234 because they were passing configuration via environment variables instead of using the config parameter.

Changes

• create_discussion.test.cjs: Updated to pass title_prefix and category via config object parameter
• update_issue.test.cjs: Updated to pass allow_title, allow_status, allow_body, and target via config object parameter
• close_issue.test.cjs: Updated to pass target, required_title_prefix, and required_labels via config object parameter

Example

// Before: using environment variables
process.env.GH_AW_UPDATE_TITLE = "true";
await main();

// After: passing config via parameter
await main({ allow_title: true });

All 118 test files now pass (2398 tests).

Done in commit 593f7ac. Reverted changes to the code files and updated the tests to pass configuration via the config parameter instead of environment variables.
