Added @graphiql/explorer-plugin in twenty docs package

[Jeong-Min-Cho]

Summary

This pull request closes #3087 and introduces crucial updates to the GraphiQL environment within the twenty-docs package. Notable changes include the installation of @graphiql/plugin-explorer, an update to graphiql version 3.0.10, and the addition of default CSS for the newly added plugin.

Changes

1. Installed @graphiql/plugin-explorer.
2. Updated graphiql to the latest version, which is 3.0.10.
3. Added a default CSS for plugin-explorer.
4. Adapted the plugin-explorer CSS to useEffect because We load graphiql style using useEffect as it breaks remaining docs style as the comment said.
5. Applied Prettier.

Known issue

1. The input box of the query name is a little smaller than the name itself.
