feat: rename ChannelPaginatorsOrchestrator to ChannelManager

[MartinCupela]

🎯 Goal

depends on GetStream/stream-chat-js#1813

Tracks the stream-chat rename of ChannelPaginatorsOrchestrator to
ChannelManager. No behavioral change on the React side.

BREAKING CHANGE: the prop and the ChatContext field
channelPaginatorsOrchestrator are renamed to channelManager, and the types
ChannelPaginatorsOrchestrator / ChannelPaginatorsOrchestratorState are now
ChannelManager / ChannelManagerState. Every useChatContext() consumer reading
the old field, and any test that builds a partial ChatContext value, has to be
updated. No deprecated prop or type aliases are exported.
