[dependabot]

Bumps github.com/ethereum/go-ethereum from 1.9.20 to 1.9.21.

Release notes

Sourced from github.com/ethereum/go-ethereum's releases.

Tavum (v1.9.21)

Geth v1.9.21 is a regular maintenance release, the highlights being the removal of whisper, better call tracing and multiple memory stability fixes during fast sync to both stabilize usage as well as to fix a memory leak that lead to crashers before.

• Remove Whisper as promised a couple months ago (#21487, #21526, #21527)!
• Minor user experience polishes around legacy Ledger derivation paths (#21517).
• Implement arbitrary call tracing via debug_traceCall on top of arbitrary blocks (#21338).
• Expose internal transaction revertals and revert reason in the call_tracer tracer (#21387).
• Cap the number of in-memory trie nodes during fast sync, fix crasher memory leak (#21491).
• Prepare the trie syncer for path-based operation to support the upcoming snap sync (#21504).
• Limit the cached data in the downloader more aggressively to avoid memory fluctuations (#21366).
• Fix the simulated chain to not allow changing block timestamps if transactions were included (#21334).
• Fix an ABI parser issue around tuples (#21501).

For a full rundown of the changes please consult the Geth 1.9.21 release milestone
