Fix accidental module replacements in tests

[jakebailey]

While cherry-picking the module changes to the tsgo-port branch, I noticed these few that appear to have been unintentional / redundant.

Pull request overview

This PR fixes accidental module-to-namespace replacements that occurred during cherry-picking changes to the tsgo-port branch. The changes restore the original module-related code and test baselines that were unintentionally replaced with namespace-related content.

Key Changes

• Restored original module keyword in test case asiPreventsParsingAsNamespace04.ts
• Removed duplicate namespace declarations in parseInvalidNames.ts test
• Corrected namespace name from placeholder "$1" to actual Unicode identifier in collisionCodeGenModuleWithUnicodeNames test files
