docs : add MTP to GGUF Type slot

Adds `MTP` as a third value for the `Type` slot (alongside `LoRA` and
`vocab`) to cover Multi-Token Prediction / speculative-decoding draft
modules shipped beside a base model. Updates the validation regex in
both the prose and JS copies, adds a filename example, and extends the
Node.js test cases.

 At a minimum all model files should have at least BaseName, SizeLabel, Version, in order to be easily validated as a file that is keeping with the GGUF Naming Convention. An example of this issue is that it is easy for Encoding to be mistaken as a FineTune if Version is omitted.
 
-To validate you can use this regular expression `^(?<BaseName>[A-Za-z0-9\s]*(?:(?:-(?:(?:[A-Za-z\s][A-Za-z0-9\s]*)|(?:[0-9\s]*)))*))-(?:(?<SizeLabel>(?:\d+x)?(?:\d+\.)?\d+[A-Za-z](?:-[A-Za-z]+(\d+\.)?\d+[A-Za-z]+)?)(?:-(?<FineTune>[A-Za-z0-9\s-]+))?)?-(?:(?<Version>v\d+(?:\.\d+)*))(?:-(?<Encoding>(?!LoRA|vocab)[\w_]+))?(?:-(?<Type>LoRA|vocab))?(?:-(?<Shard>\d{5}-of-\d{5}))?\.gguf$` which will check that you got the minimum BaseName, SizeLabel and Version present in the correct order.
