release: v0.10.5

[Mirko-von-Leipzig]

Preparation branch for releases v0.10.4 and v0.10.5.

Current main with PRs #1715, #1694 and #1679 reverted. Revert commits were created using

git git rev-list --ancestry-path <PR-HEAD>..<PR-TAIL>
git revert --no-commit <EACH-SHA-FROM_ABOVE>
git revert --no-commit <PR-HAD> (this isn't included by rev-list)
git commit

Includes additional commits to fix things broken by the reverts e.g. rpc v0.4 didn't have support for trace caching.

• wait for trace request coalescing no longer happening
• reorder commits so that we can include only the UNEXPECTED ERROR spec fix as release v0.10.4 and exclude the PRs that we've reverted.
• tag head of this branch as v0.10.5.
• update changelog on main with v0.10.4 and v0.10.5 releases.
