Subject: [PATCH] `eth-json-rpc-provider` migration - B4: Add exceptions in
 `constraints.pro` for ISC license. (#1767)

## Explanation

This PR implements the following incremental step in the process for
migrating `eth-json-rpc-provider` into the core monorepo:

***

### Phase B: Staging in `migrated-packages/`
#### 4. Add exception for non-MIT license.
- [x] If migration target uses a non-MIT license, add exception entries
in the root `constraints.pro` file.
- [x] Make sure the new rule doesn't break any of the existing
package.json files by running `yarn constraints`.

***

See https://github.com/MetaMask/core/issues/1551#issuecomment-1745665740
for an outline of the entire process.
