Streamlabs Donation Handler [Bug + Fix]

[MiahFuta]

Sorry, I'm far too lazy to do a pull request, but this bug has been here for ages and it's rather annoying.

PhantomBot Version: EVERY
O/S Version: ANY
Java Version: ALL

Detailed Description:
Wrong Parse Method Used

Steps to Reproduce:
Any donation that's not an even dollar amount
In the screen shot below, both donations were added with 16.92
Though as you can see, the first one, with the old code, rounds down.
But the second one, with the new code, shows the correct donation amount.

The Fix:
Change parseInt, to parseFloat on line 64 in scripts/discord/handlers/streamlabsHandler.js

Before:
s = $.replace(s, '(amount)', parseInt(donationAmount).toFixed(2).toString());
After:
s = $.replace(s, '(amount)', parseFloat(donationAmount).toFixed(2).toString());
