docs(readme): New logo & Readme(s) revamp

[mateobelanger]

This pull request includes updates to configuration files and documentation improvements. The changes primarily focus on updating the README.md files for better clarity and adding new badges and examples.

For now the rig & playgrounds logos are added as files to the repo. If you agree with the style changes I'll move the files to the rig-site repo and switch to hyperlinks.

Documentation Updates:

• README.md: Updated logo sources, added new badges, improved wording, and added new sections for getting started and integrations. [1] [2] [3]
• rig-lancedb/README.md: Updated the introduction with logos and added usage instructions.

interesting, i'm not sure about "By" not being aligned w/ "Playgrounds". Otherwise, it's very nice!

Thanks for the feedback! Yeah bizarre quirk of svg because in my editor it's aligned. Will probably have to use png/jpeg.

Nice work! But there are a few things to change. Also, the README example is outdated and should be:

use rig::{completion::Prompt, providers::openai};

#[tokio::main]
async fn main() {
    // Create OpenAI client and model
    // This requires the `OPENAI_API_KEY` environment variable to be set.
    let openai_client = openai::Client::from_env();

    let gpt4 = openai_client.agent("gpt-4").build();

    // Prompt the model and print its response
    let response = gpt4
        .prompt("Who are you?")
        .await
        .expect("Failed to prompt GPT-4");

    println!("GPT-4: {response}");
}

(change openai_client.model to openai_client.agent)

This seems wrong / duplicates.., might want to clean this up
