Submit Update committee/threshold Discovery Governance Action

For this GA can we display the CC member instead of the key? (the info that is on the CC Portal), so that the user can understand what are keys referring to

What are the implications of this GA?
How should we display it on govtool? (considering most info are metadata)
Should we support an easy process to submit one?

Add the scope and parameters of the "Update committee/threshold" here to help with screen and flow design.

What is this action all about?
What are it's parameters?
What inputs need to be entered by users?
What outputs need to be served to users?
What are the technical implications?
Anything else?
