fix(deps): surgical yarn.lock fix for scrypt-shim malware

Replace malicious `scrypt-shim@github:web3-js/scrypt-shim` (MAL-2022-5972)
resolved from codeload.github.com with the npm security placeholder
`0.0.1-security` in solidity/ecdsa and solidity/random-beacon yarn.lock
files.

Restores lock files to main-branch state (valid npm registry references)
to fix the CI SSH auth failure caused by the previous regenerated lock
files containing git+ssh:// references to private repos.

Also removes the `resolutions: web3-eth-accounts` field from both
package.json files — it was not compatible with --frozen-lockfile CI.
