[Maturity] Updated Support Dimension Excel Sheet

Hola equipo,
Please find attached the last version we have on the MM spreadsheet.
Employee Support section:
I added the decisions we took and edits we decided together and pending
rewrite.
From Organizational support on:
We agreed on the content of all the points moving forward but identified

mandatory tone.

Please let me know if you have any questions,
