Consider adding verification step at the end of migration tool

[rootulp]

Context

https://docs.helium.com/solana/migration/ledger/#migration-tool

Problem

After the last step, there is no verification step. It would be helpful if the docs described a step so that one can manually verify that the migration completed successfully.

Proposal

I imagine that step would look like:

1. Find the public address associated with your pre-migrated account. Note: how do I do this?
2. Search for your old public address on https://explorer.solana.com/ and ensure the account has no funds
3. Find the public address associated with your post-migrated account.
4. Search for your new public address on https://explorer.solana.com/ and ensure the account has some funds

Note:

• I'm observing some residual Helium Network Token in the pre-migrated account. If this is expected behavior, I think it should be documented here.
• It would nice to add a note that says something like: "staked HNT will be migrated to a single veHNT token" with a link to docs on the veHNT token.
