**Description of the issue:**  
When using a Trezor-backed wallet in the Crypto Wallets tool, every time I have to do something on the Trezor device, I get a warning window saying the following:  
"The current version of firmware (2.3.4) may be not compatible with the running version of Trezor Connect. "

While everything is functioning fine so far, since crypto stuff is tech-sensitive, just wanted to let you guys know you should upgrade the version of Trezor Connect middleware you embed in Brave. Thanks!

**Steps to Reproduce (add as many as necessary): 1. 2. 3.**

1. Set up a wallet in the Crypto Wallets tool backed by a Trezor device
2. Make sure Trezor device firmware is up to date
3. Try to do any crypto transcation (e.g. sign a message through Metamask)

**Actual Result (gifs and screenshots are welcome!):**

**Expected result:**  
Trezor does not complain about Trezor Connect version mismatch.

**Reproduces how often:**  
Every time I do an action that requires interaction with Trezor

**Operating System and Brave Version(See the `About Brave` page in the main menu):**  
Windows build 19041  
Brave Dev 1.16.63
