Clarify the usage of the term `peer`

[chacha912]

Description:

The term peer generally does not include oneself. However, in the context of Yorkie, the word peer is used to refer to other clients, including the current one. To avoid confusion, ensure that the term peer is consistently used to represent other clients, and when referring to both peers and oneself, use terms like users or clients. (It is also required in the examples)

Why: Clarify the usage of the term peer

Currently, in Yorkie project, we represent User as a user of the dashboard. I understand that there is a need for an expression that can combine Presence and ClientID in the SDK, but I'm wondering if there might be a better word. 🤔

I'm also waiting for other people's opinions.

The term Peer can be found in the examples and documentation, but it does not appear to be used in source code. So, I'll close this issue for now.
