Upgrade to latest `@stacks/wallet-sdk`

[kyranjamie]

We need to upgrade the wallet-sdk to the version including @friedger's PR stx-labs/stacks.js#1204

This will fix profile signing for new users

To add to the context, I saw that a commit with 3.4.0 release was created but I couldn't find the tag on npm so maybe something went wrong during the release process.

Will need to address this when we do the update: #2282

@kyranjamie @pradel Can one of you spell out the exact problem that will or does occur already without this upgrade, so that we capture clearly here the specific UX benefit to this upgrade?

[pradel]

This fix is for signing the profile.json with the right key, no UX changes are required.

[markmhendrickson]

I mean to ask, what UX problems will occur if we don't make this upgrade (aside from us needing to make any UX changes per se, since I agree those aren't required)?

In other words, what will go wrong exactly (e.g. with Sigle usage) if we don't upgrade how the profile.json is signed? I presume something akin to what we outlined here in Notion, but would like to capture here on GitHub as well.

From the notion, the part not working is:

• Accounts displayed all the same as before
• Others attempting to view sigle.io/mary.id.blockstack/mypost can view her blog post
• Others attempting to view sigle.io/mary1.btc/mypost cannot view her blog post

The profile.json is signed with the wrong key, so when we fetch the profile we can't verify that mary1.btc did sign it properly.
