Simplifies the Babel configuration by removing transformations that are no longer needed, and replacing them with relevant presets.

This change is needed to land patternfly/patternfly-react#10189

I've removed all the individual Babel transformations, since @babel/preset-env will already handle these automatically. I've also replaced @babel/plugin-transform-react-jsx with @babel/preset-react, which can do more in-depth optimization.

I've removed the core-js auto-polyfilling and related settings here. The reason for that is with useBuiltIns set to entry it is required to add an explicit import to core-js in the application code (see documentation).

Since the aforementioned import never existed in the application code this essentially means that core-js polyfills were also never included. So I have opted to plain out disable it to make this more explicit.

I've removed these transforms, as they are now implicitly no longer included by updating the targets field, as well as updating the browserlist database (change included in updated lockfile).

I've removed the modules field here, as this should be left to auto (the default) when using it in combination with a bundler such as WebPack + babel-loader, which is the case here (see documentation).

I've narrowed the support target, as this was matching a lot of unsupported browsers. The new target still has wide support for various browsers, but prevents excessive transpilation.

All these plugins are already supported by @babel/preset-env, so there is no need to specify them individually.
