Pull request overview

This PR re-ports test cases for the typescript/prefer-as-const rule from the upstream typescript-eslint project. The changes expand test coverage by adding more test cases for both passing and failing scenarios.

Changes:

• Reformatted existing single-line class test cases to multi-line format for better readability
• Added new test cases for object properties and as expressions
• Simplified fix test case format from 3-tuple to 2-tuple (removing unnecessary None parameter)
• Updated snapshot file to reflect the new test cases
• Preserved commented-out test cases for TSX angle bracket syntax that OXC doesn't yet support
