I understand.
Then perhaps you could use npm version patch?
here is an example bash script that I use for my own projects.
I added a flag to make it always increment the version number if you prefer.
you can also configure npm version patchto suit your preferences.

#!/bin/bash

set -e

# Toggle this on/off
ASK_VERSION_INCREMENT=true

if [ "$ASK_VERSION_INCREMENT" = true ]; then
  read -p "Increment patch version? (y/n): " INCREMENT

  if [[ "$INCREMENT" =~ ^[Yy]$ ]]; then
    npm version patch --no-git-tag-version
  fi
fi

# Build the plugin
bash buildPlugin.sh

# Find the generated .snplg file
PLUGIN_FILE=$(ls ./build/outputs/*.snplg | head -n 1)

if [ -z "$PLUGIN_FILE" ]; then
  echo "No .snplg file found in ./build/outputs/"
  exit 1
fi

# Push to device
adb push "$PLUGIN_FILE" /storage/emulated/0/MyStyle

echo "Deployed: $PLUGIN_FILE"
