Two changelog files, please change that.

Two changelog files, please change that.

This is intentional, there's one changelog file we're adding in this PR, and one we're changing from a previous update to the Falco Chart. Otherwise we'd have two entries for this in the release changelog, which we don't want.

The backport to release-v3 failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-release-v3 release-v3
# Navigate to the new working tree
cd .worktrees/backport-release-v3
# Create a new branch
git switch --create backport-3415-to-release-v3
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 2d6d1c6c058941123119f60a54e41de340da8c86
# Push it to GitHub
git push --set-upstream origin backport-3415-to-release-v3
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release-v3

Then, create a pull request where the base branch is release-v3 and the compare/head branch is backport-3415-to-release-v3.
