Support for eslint 9

[Santalov]

This project comes with eslint config out of the box.

But eslint is not listed in the project deps. So running lint script errors.

The next obvious step is to install eslint

yarn add eslint

But by default latest version of the eslint is installed (eslint 9), which is incompatible with current config file. So developer meets unobvious errors which is a little frustrating.

You can see the first details about new config format here. And some examples are here https://stackoverflow.com/questions/74237042/how-to-correctly-configure-the-parser-plugins-with-eslints-new-flat-config

I suggest eslint configuration should be removed or updated to meet the latest version of eslint.

Hey. Missing eslint package seems like a bug.

I am not sure we can switch to eslint@9 as long as it seems rather new for now and some of the plugins are not ready for a new major version.

Nevertheless, we can possibly recognize current eslint configuration as too subjective and remove all plugins just leaving only those, necessary for working with TypeScript. So, we would use some config like eslint/recommended. In this case, we can switch to eslint9.

What do you think about it? In case, its fine, could you create a PR proposing changes?
