Hi, there!! Hope this isn't an unwelcome contribution.

The jotai functions currently display deprecation notices surrounding the use of several functions, especially those from jotai/utils.

fix #259

Motivation and Context

We use the @MetaMask/open-rpc-docs-react package for our Docusaurus site. Every time we build, there are many deprecation notices, just like is mentioned in issue #259. I've experimented with locally applying a patch to the package once downloaded, and the deprecation warnings disappear. This PR is a more "proper" form of that fix.

Description

This change migrates to the newer functions recommended by the deprecation notices. To accomplish this,

• I've removed all imports from jotai/utils.
• useAtomValue is now imported directly from jotai instead
• useUpdateAtom (from jotai/utils) is replaced by useSetAtom from jotai.

How Has This Been Tested?

I've made the same changes to the node_modules version of this package in my local Docusaurus site, and the build proceeds with no deprecation notices.

I've also run the yarn test.prod script, and all tests pass. The functions I've used to replace the deprecated ones seem like drop-in replacements, and there shouldn't be any trouble. In this (old) commit in the jotai package, they're using these same functions "internally" for these deprecated functions I'm replacing.

I'm not sure if it's necessary to add error reporting or more test cases for a change this "simple," but I'm more than happy to add them if it's required.
