chore: bump eslint to the latest version

[mman]

also not as simple as it looks...

... but doable, done for influx loader and it works great.

a bit of history. Venus HTML5 app was based on https://create-react-app.dev which started as a promising wrapper around webpack and its plugins but ended up in a state where it is no longer maintained and stuck on couple older dependencies.

More over when using CRA, one can not easily override the defaults so a process called npm run eject was performed in order to basically discard CRA and produce bunch of complicated ./config/ files and ./scripts that perform the build and testing.

Notably the scripts in ./scripts folder depend on couple outdated dependencies that are not updated for eslint 9 and that apparently are not being worked on.

One of them is https://github.com/facebook/create-react-app/tree/main/packages/eslint-config-react-app that hard depends on eslint 8 and is being hardcoded in the webpack.config.js

And there are couple more that are hardcoded in the webpack.config.js not doing much real work, just complicating the update process.
