Typescript conversion of Paperbase theme

[waynevanson]

• I have searched the issues of this repository and believe that this is not a duplicate.

Summary 💡

I have a Typescript conversion of this theme ready to go but I need a place to put it.

Would you prefer this example in typescript only, or have them side by side in seperate folders? I've got the example ready to go.

Examples 🌈

In the bank, just let me know how to go about it.

Motivation 🔦

Add typescript version of the theme.

Quote from #16969, relating to this theme and types.

This bug wouldn't have happened if paperbase was in typescript. That alone is an improvement and not a myth.

I know ya'll getting hammered with 'convert this to Typescript' and I do agree, with the size of the project being the only drawback. I find that VScode's TSserver is slow when using MaterialUI, but is fast when using any other UI framework with types. Either way, let me know where to pull this into :)
