documentation: how to extend slidev with addons and add custom transformers

[RudolfVonKrugstein]

Describe the bug

It is unclear to me, how and if slidev can be extendend and add custom transformers. Looking at the example addons I can see that I can add custom components via addons.
What I want is add a custom transformer, so that I can add another block type (like mermaid, plantuml etc.,).

To Reproduce
Looking through the documentation, I find the addon section. It tells me, what addons can do. Transformers are not part of it, so I am unsure if there is any way of doing this.

Desktop (please complete the following information):

• OS: Linux (Pop-OS)
• Browser: brave
• Slidev version: 0.40.3

You are right, this not stated in the documentation but you should be able to provide a vite.config.ts file in an addon that you can use to extend the vite configuration and add transformers.
Check how to customize vite here: https://sli.dev/custom/config-vite.html
please tell me if it works for you.
