Add support for community shards

[0x-r4bbit]

At the time of writing this issue, community description data is retrieved from a waku topic that is derived from the community's ID. These topics live within the waku base topic namespace.

With shards, community topics/channels can exist in a shard, kind of like a "sub" topic.
To support votes for sharded communities, we need to adjust the voting data to included the community's shard index.

@mprakhov would you say your work fixed this issue or something needs to be done in the community-dapp code as well?

I'm not familiar with voting dapp, but based on the comment

@jrainville It seems we need to provide (or check) to vote dapp shard info and update this shard info in dapp if the community changes shard (I didn't do that)
