fix(rpc): align fee history (backport #1611) (#1620)

* fix(rpc): align fee history (#1611) * update nix * add next fee in fee history * fix test * add change doc * height + 1 for next fee * cross check baseFeePerGas len * Update tests/integration_tests/test_fee_history.py Co-authored-by: MalteHerrmann <42640438+MalteHerrmann@users.noreply.github.com> * fix oldestBlock & align earliest input as eth * update doc * update nix * isort test_fee_history.py * fix test * align rpc res as eth * add cross check * add baseFeePerGas len check * add oldestBlock check Co-authored-by: MalteHerrmann <42640438+MalteHerrmann@users.noreply.github.com> Co-authored-by: Federico Kunze Küllmer <31522760+fedekunze@users.noreply.github.com> (cherry picked from commit 47fdfd3d8318358c2578b610bc35bc8c1ebb131e) # Conflicts: # CHANGELOG.md * address merge conflicts Co-authored-by: mmsqe <mavis@crypto.com> Co-authored-by: MalteHerrmann <malte@evmos.org> Co-authored-by: Federico Kunze Küllmer <31522760+fedekunze@users.noreply.github.com>
