Update client-side-cacing.md

[Virusuki]

If i don't look closely the explanation in client-side-caching, I think the Database term is ambiguous.
Because it can be thought of as the entire database, it would be better to specify it as a valkey.

Also, change channel name the redis:invalidate to valkey:invalidate.

It would be a breaking change to change client-side caching like that. (Obviously you didn't test it. 🙂) There's a PR about it, but it's not yet decided how we can do it to avoid breaking clients.

Changing the word database in the text is OK, but the name is Valkey, not valkey.

I know there are side effects to changing redis:invalidate.
I'll have to think carefully about it PR #410.

Additionally, I changed it to "database" -> "Valkey".

Thanks! It like to merge this change first.
