use_bridge hook for agents

[futursolo]

Description

This PR adds a use_bridge hook to yew-agent which does the following:

• Bridges to the specified agent once throughout the entire lifecycle of the component.
• Update the Callback to be the latest every time the component is rendered to prevent stale values in the callback.

Fixes #2112 (Partially)

Checklist

• I have run cargo make pr-flow
• I have reviewed my own code
• I have added tests

[futursolo]

The clippy error is solved in #2126.

I love the idea of having a dedicated hook for connecting to agents.

Could you also add documentation for this new hook?

I think the documentation of yew_agent::use_bridge belongs to the agent section, not the pre defined hooks section since it is not in the yew crate or yew::prelude.

However, the docs for agents currently do not have any information on how to actually use them which is why I didn't add any documentation.

@futursolo My view on this would be that having documentation, even if its in a not separate place would be good.
Perhaps It will be worth to refactor out agents section or something in the future, but for this PR scope, having something in pre-defined hooks section, in my opinion, would be enough.

@futursolo Further looking at the docs I see that under https://yew.rs/next/concepts/agents#bridges adding simple mention about this hook would probably be enough.
