ci: bump tree-sitter/parser-test-action from 2 to 3

[Copilot]

Bumps tree-sitter/parser-test-action from v2 to v3. The v3 action defaults to Go 1.22, but go.mod requires Go 1.23, causing CI failures.

• Added go-version: "1.23" to the parser-test-action configuration to match go.mod requirements

  uses: tree-sitter/parser-test-action@v3

    test-rust: true
    test-python: true
    test-go: true
    test-swift: false
