webpack cleanup

[gathuku]

@excid3 can we remove this file containing webpack related content?. We are using the esbuild-rails plugin to load all files with the suffix _channel.js. Someone may not notice the errors but when you import everything in the channel directory(import "./channels") the errors are visible in the console and can cause issues.

require.context is a special feature supported by webpack's compiler that allows you to get all matching modules starting from some base directory

It does need to be replaced with esbuild import.

Instead of removing channels/index.js, we can just replace the contents with an esbuild import like we do with Stimulus controllers.

import "./**/*_channel.js"

Also I think we can remove app/javascript/packs folder since it's not being used anymore.

Please check how the custom.js we can handle custom.js for bootstrap tooltips.
