Update the visualizer to match the latest version of FSRS-5

I don't think that the current version of the visualizer is fully up-to-date

This repository uses version 4.4.2 of this library: https://github.com/open-spaced-repetition/ts-fsrs

And it is the latest version for today: https://github.com/open-spaced-repetition/ts-fsrs/releases

What exactly is not up to date? Can you give some example?

Visualizer:

The difficulty formula has recently been updated. Perhaps ts-FSRS hasn't been updated?

I found that FSRS-Optimizer added linear damping here: open-spaced-repetition/fsrs-optimizer#143

It is already implemented in open-spaced-repetition/fsrs-rs#239 and in open-spaced-repetition/fsrs4anki#702

But neither ts-fsrs nor py-fsrs nor rs-fsrs have added it yet.

So I will wait for open-spaced-repetition/ts-fsrs#133 to catch up with it.

Perhaps ts-FSRS hasn't been updated?

ts-fsrs has not yet approved the merge of linear damping. Please wait for the stable release of Anki.
