Fix: Corrects the generation of the hash variable name

[AlanMartines]

Corrects the generation of the hash variable name, error when generating with white spaces and special characters.

Error:

{
  "status": 500,
  "error": "Internal Server Error",
  "response": {
    "message": "Command failed: /root/evolution-api/node_modules/@ffmpeg-installer/linux-x64/ffmpeg -i /root/evolution-api/store/temp/temp-+55 (99) 9 9999-9999-1704891424843.mp3 -vn -ab 128k -ar 44100 -f ipod /root/evolution-api/store/temp/+55 (99) 9 9999-9999-1704891424843.mp4 -y\n/bin/sh: 1: Syntax error: \"(\" unexpected\n"
  }
}

Fix:
Added the parameter number = number.replace(/\D/g, ""); before the line const hash = ${number}-${new Date().getTime()}; to remove any non-numeric characters in the processAudio function.
