Subject: [PATCH] fix: Send correct message action from ledger offscreen bridge
 to ledger bridge (#24622)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## **Description**

Fixes a bug. Personal signatures were broken for ledger on MV3. The
problem was that the offscreen bridge named those message actions
incorrectly. The ledger bridge expects `'ledger-sign-personal-message'`:
https://github.com/MetaMask/eth-ledger-bridge-keyring/blob/gh-pages/ledger-bridge.js#L35-L37

This is consistent with the implementation of `deviceSignMessage` on the
current iframe bridge:
https://github.com/MetaMask/eth-ledger-bridge-keyring/blob/main/src/ledger-iframe-bridge.ts#L219-L226

Fixes: https://github.com/MetaMask/metamask-extension/issues/24588

## **Manual testing steps**

1. Build MV3
2. Import a ledger
3. Go to the test dapp
4. Try a Personal Sign
5. Accept in MM
6. You should see the signature on your ledger and be able to
successfully sign
