Update update-cloudflared.mdx (#21868)

Change Description
This pull request proposes changing the command sudo apt-get upgrade cloudflared to sudo apt-get update && sudo apt-get upgrade cloudflared to ensure cloudflared is updated correctly.

Justification
The command sudo apt-get upgrade cloudflared does not update cloudflared if the package list is not up-to-date. By adding sudo apt-get update, we ensure the package list is updated before attempting to upgrade cloudflared.

Evidence
Below is the evidence showing that cloudflared does not update correctly without the sudo apt-get update command:
