Set duration period for DAO Committee members

The absence of a period of duration for DAO committee members in Decentraland can lead to several potential issues, including:

Lack of accountability: Without a set term, committee members may not be held accountable for their actions, leading to potential abuses of power.

Lack of fresh perspectives: Without new members regularly joining the committee, the same individuals may hold power for an extended period of time, stifling innovation and new ideas.
