Upgrade devtools dependency update-notifier to 5.x (#31655)

## Summary

This PR upgrades the dependency on update-notifier, used in
react-devtools, to 5.x
This is the latest non-ESM version, so upgrading to it should be
unproblematic (while updating to 6.x and beyond will have to wait).

Upgrading means we avoid installing a lot of outdated dependencies (as
can be seen from the diff in yarn.lock), and resolves part of
https://github.com/facebook/react/issues/28058

Changelog:
https://github.com/yeoman/update-notifier/releases

The most relevant breaking change seems to be that the minimum support
node version is increased from v6 to v10, but I couldn't find what is
currently React's official node version support.

## How did you test this change?

I ran the test-suite locally (`yarn test` in root folder), but I'm not
sure if that one actually covers devtools?

I also built and tested this version of devtools with some internal
company projects (both react and react-native based) – following
guidelines from
https://github.com/facebook/react/issues/28058#issuecomment-1943619292.
