Resolve BNSv2 names instead of BNSv1 names on the explorer

[314159265359879]

Is your feature request related to a problem? Please describe.
Using two BNS contracts to resolve, this would cause confusion. The community is quickly adopting the BNSv2 contract because of the improvements (such as allowing more than one name per address and listing from a wallet non-custodially).

Leather is only displaying the BNSv2 name since version 6.52.0 and hiding the v1 name (and hiding the airdrop with the mistake). Although I do think it makes sense for users on marketplaces and explorers to still see the BNSv1 names, they may still hold collectors' value.
Gamma.io and Tradeport are also working on supporting BNSv2 instead.

A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

Describe the solution you'd like
Resolving to Stacks addresses in the explorer search bar should only resolve to the BNSv2 names to prevent confusion.

Additionally it would be great if in the sandbox explorer a link was added to the BNSv2 address (instead or in addition to the BNS contract in the genesis address): SP2QEZ06AGJ3RKJPBV14SY1V5BBFNAW33D96YPGZF.BNS-V2

Describe alternatives you've considered
Resolving both and letting the user choose if they want to check the Stacks address associated with the BNSv1 name or the one associated with the BNSv2 name.

I think it is better to regard BNSv2 as the BNS contract, BNSv1 is the legacy contract which is no longer used or only until everyone has migrated and adopted the BNSv2 contract. I think it would be great if Hiro can help lead the way.

Important! Thanks Werner.

@zone117x do we have a new API that supports bns2? e.g. get address that is associated with a particular bns name?

[zone117x]

IIUC bns2 is all on-chain now, so likely involve RPC contract-calls and maybe NFT related endpoints. I'm not sure though, I'd recommend taking a look at the bnsv2 spec or code.

There's also https://github.com/Strata-Labs/bns-v2-sdk if that's easier to integrate with.
