To provide IP ranges in the detection fields of a rule, we need to support the cidr modifier option. This PR adds that option in the dropdown. It also fixes a couple of edge cases for detection parsing

The backport to 2.10 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-2.10 2.10
# Navigate to the new working tree
cd .worktrees/backport-2.10
# Create a new branch
git switch --create backport/backport-693-to-2.10
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 7e5985fbdeed097f545cede1ffd0b2a5710271d2
# Push it to GitHub
git push --set-upstream origin backport/backport-693-to-2.10
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-2.10

Then, create a pull request where the base branch is 2.10 and the compare/head branch is backport/backport-693-to-2.10.
