Usage:
  scripts/update-nomos-rev.sh --rev <git_rev>
  scripts/update-nomos-rev.sh --path <local_dir>
  scripts/update-nomos-rev.sh --unskip-worktree

Notes:
  --rev   sets NOMOS_NODE_REV and updates Cargo.toml revs
  --path  sets NOMOS_NODE_PATH (clears NOMOS_NODE_REV) and patches Cargo.toml to use a local nomos-node checkout
  --unskip-worktree clears any skip-worktree flag for Cargo.toml
  Only one may be used at a time.
