Pull request overview

This PR fixes a bug where JSX fragments were missing a leading semicolon when the formatter's semicolon option is set to "AsNeeded". The fix ensures JSX fragments are handled consistently with JSX elements when determining if an expression statement needs a leading semicolon to prevent ASI (Automatic Semicolon Insertion) issues.

• Added Expression::JSXFragment(_) to the pattern match in expression_statement_needs_semicolon function
• Fixed 6 TypeScript test cases that were previously failing to parse
• Improved test coverage from 99.40% to 99.46%
