Previously available content is missiong - OWASP_MAS_Checklist.xlsx #210

Describe what content should be added :

There are OWASP resources that reference a MAS Checklist excel file, and link it as being at:
https://github.com/OWASP/owasp-mastg/releases/latest/download/OWASP_MAS_Checklist.xlsx

However the file is not there. I searched the repository for all .xlsx files and found another referenced link to the file, but that one is also dead. Please restore this file.
