Upgrade with-reasonml-todo to with-rescript-todo example

[ryyppy]

Follow up to #24898

ReasonML & BuckleScript have officially rebranded to ReScript, so I'd like to deprecate with-reasonml-todo in favour of a with-rescript-todo example.

I updated all the dependencies and converted the original example to ReScript / React.
