* Update `eth-json-rpc-infura` The package `eth-json-rpc-infura@5` has been updated to `@metamask/eth-json-rpc-infura@7`. This update includes TypeScript support, and it drops support for older node.js versions. The exports have also been changed from default to named exports. See here for a full list of changes: https://github.com/MetaMask/eth-json-rpc-infura/blob/main/CHANGELOG.md#700 * Fix LavaMoat policy issue The `web3` package used by `@metamask/controllers` unintentionally overwrites the `XMLHttpRequest` global, which breaks things. This was fixed by revoking `web3`'s write access to that global using a policy override. Previously this policy override was applied to `web3`, but for some unknown reason, this update caused that override to no longer apply.
