Small issues in 0.5.0 docs

[ochrons]

1. the 0.5.0 docs should explicitly tell users to install the 0.5.0 version of CLI cargo install dioxus-cli@0.5.0-alpha.0 since the older CLI versions are not fully compatible (https://dioxuslabs.com/learn/0.5/getting_started/wasm)
2. Dioxus CLI readme should also have installation instructions for 0.5.0
3. pointing users to a very old blog post (https://dioxuslabs.com/blog/introducing-dioxus) on the first intro page might not be the best idea
4. examples for Liveview https://dioxuslabs.com/learn/0.5/getting_started/liveview for Salvo and Warp do not exist anymore. I suppose these should also be dropped from https://dioxuslabs.com/learn/0.5/getting_started/fullstack
5. CodeSandbox is out of credits, for example on https://dioxuslabs.com/learn/0.5/reference/fullstack/server_functions
6. In https://dioxuslabs.com/learn/0.5/reference/use_resource the dependencies example doesn't actually provide a tuple of dependencies. Is it even possible with use_resource?
7. In the same page the first example could be simplified to

    let mut future = use_resource( || async {
        reqwest::get("https://dog.ceo/api/breeds/image/random")
            .await
            .unwrap()
            .json::<String>()
    });

8. On the same page it says We can use .value() to get the result of the future. but the example uses read(). Calling it as future is misleading as it's a Resource<impl Future>
9. On the same page it says The UseFuture handle provides a restart method but this a Resource now
10. In https://dioxuslabs.com/learn/0.5/guide/data_fetching there should be an instruction on adding reqwest and serde crates
11. Example on https://dioxuslabs.com/learn/0.5/reference/fullstack/server_functions could be simplified as

let count = use_server_future(get_server_data)?;

The returned value is Some(Ok("Hello from the server!")) instead of Ok("Hello from the server!")

There is also a little typo there, in the snippet for installing Manganis cargo add maganis "maganis" instead of "manganis"
