exclude emeritus from voting overview

[derberg]

we show voting overview in https://github.com/asyncapi/community/blob/master/TSC_VOTING_OVERVIEW.md

data file is here: https://github.com/asyncapi/community/blob/master/voteTrackingFile.json

all implementation details are in: #1278

the thing is that we should not show in the voting overview people that are no longer TSC members but emeritus

example of person that is visible in voting, but no longer tsc member: https://github.com/asyncapi/community/blob/master/MAINTAINERS.yaml#L194
