Rename extension name from polkadot-js to nova-wallet

[laurogripa]

I'm opening an issue here because it seems like a more appropriate place.

You can check another issue opened by another user on the js dapp repo (& my reasoning) in this link, but I will replicate most of my comment here too for clarity...

Right now, Nova's extension name is polkadot-js, which can be confusing for new dapps trying to add Nova support. They have to implement a workaround, treating Nova's extension name as polkadot-js, and using mobile detection to differentiate between mobile & desktop browsers to decide which polkadot-js to show, or else it can get very confusing for users.

It's the case for Hydra's UI, see here:

And here:

It's not a huge problem, it can be worked around, but it's a bad DevX for newcomers. It sounds like a very simple fix, we just need to be aware that changing the extension name might break a lot (if not all) UIs that support Nova in the ecosystem. I think it needs to be a coordinated fix.

Hey Lauro! Thank you for raising the issue. We are planing to add a separate extension name for the Nova Wallet. I will let you know in the issue once it is done.
