Refs are stuck with their initial values. Ref mutations are not reflected in the hook return value

[DavidKrpt]

Here's a minimal reproduction repo made with CRA
https://github.com/DavidKrpt/ref-issue-in-react-singleton-hook

Initially tested with react 16 and react-singleton-hook 3.4.0.
But for a quick minimal app I used CRA, and it came with react 19.
There's a peer dependency issue with react 19, so npm install needs to be done with --force
But it works the same way regardless. Just install with force, start, open the page at localhost:3000 and check the console.

Obviously, the example code makes little practical sense, it's just there to illustrate the issue.
Initially I was trying to have a shared mutable object available at different parts of the component tree, but couldn't make it work with react-singleton-hook. So I ended up using context. I think plain old global variables would also do the trick, but I was trying to do things the react way
