metamask-ledger integration issue

Reported by @fredriksvantes (🙌). Quote his words:

### Issue
My tests shows that metamask-ledger works fine on websites like app.uniswaporg, but not on the launchpad. i tested with two different OS and two different browsers on each OS, and the latest ledger firmware. it provides this error message:
"Ledger: Condition of use not satisfied (denied by user?) (0x6985) after pressing confirm in metamask.

### Possible root cause

Locally, i updated the web3, web3-utils, all @ethersproject and all `@web3-react packages` to their latest version, but it's still not working. my guess is something stopped working with the `@web3-react/injected-connector`, which can't be updated as it has been deprecated in favor of the "metamask" package: https://github.com/Uniswap/web3-react/tree/main/packages/metamask

Hi @wackerow, do you have bandwidth to help investigate how to switch our metamask package dependency?

I suppose it has to be fixed based on the node.js & web3 package upgrade fix (#543)
