feat: stop-backend.js and update.js linux support (#712)

* chore(dependabot.yml): update target-branch from "develop" to "dev" for npm package updates in /api, /client, and root directory

* feat: stop-backend.js and update.js linux support (#701)

* feat: stop-backend.js and update.js linux support

* feat: update.js sudo support

* chore(helpers.js): add deleteNodeModules function
feat(packages.js): add script to delete node_modules and install dependencies
refactor(update.js): remove unnecessary imports and use deleteNodeModules function
feat(package.json): add update:linux script to update with sudo

* chore(package.json): rename 'update:linux'  script to 'update:sudo'

* refactor(update.js): simplify downCommand and buildCommand by removing redundant use of sudo command, add sudo to single docker command
