fix: Update BNB Universal Router address

[kiseln]

Spotted an error on Deployed Addresses page.

The correct address on Binance smart chain seems to be https://bscscan.com/address/0xeC8B0F7Ffe3ae75d7FfAb09429e3675bb63503e4

And this is the one that's currently in the docs: https://bscscan.com/address/0x5302086a3a25d473aabbd0356eff8dd811a4d89b
