Include visualisations to enhance user understanding when going through the docs

[DMills27]

Description

The inclusion of more visualisations such as diagrams, flowcharts, and/or gifs would greatly benefit the documentation website. This is apparent in sections such as How Sigstore works and Software supply chain security and where the descriptions given lends itself to more visual imagery. Moreover, In the Main Concepts page, it is mentioned that “[the various sigstore technologies] can be used independently or as one single process,” yet this seems like a missed opportunity to use a diagram to Illustrate this. Visualisations reduce ambiguity and potential misunderstandings by providing a clear and precise representation of the information being conveyed. The sigstore documentation website has many sections that could be better elucidated with the addition of visual components.

Interestingly, the sigstore.dev site does a better job of utilising visualising the relationships between sigstores constituent repositories, as shown below.

Creating visualisations in a manner consistent with the rest of the site as shown in the above image would make the documentation much easier to understand compared to purely textual descriptions.

@DMills27 I do agree! Adding visualizations will surely enhance the top-down view & simplify the readability of the flow.
