Closes #4443

[l-trotta]

@georgewallace I have hardcoded the table that will be in a file just to output a quick preview, if the output is okay then I'll proceed with the implementation!

Output looks good. Thanks @l-trotta

@swallez not sure about how to pass the file, should it be another cli input? or just a constant since it won't change? should I worry about file system separators? we've decided to hardcode it since it won't change

# Create a new working tree
git worktree add .worktrees/backport-9.0 9.0
# Navigate to the new working tree
cd .worktrees/backport-9.0
# Create a new branch
git switch --create backport-4511-to-9.0
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 040e99de6b0a8876cd0d1c6f639ef91c29333345
