Revert "chore: use zstd compression for internal otlp data"

[swiatekm-sumo]

This reverts commit c185803. See: open-telemetry/opentelemetry-collector#8216.

I'm going to backport this fix to 3.12 and 3.11, as it's quite disruptive.

git worktree add .worktrees/backport-release-v3.11 release-v3.11
# Navigate to the new working tree
cd .worktrees/backport-release-v3.11
# Create a new branch
git switch --create backport-3197-to-release-v3.11
