Add an example to the descriptors glossary entry

[GBKS]

There were some questions around what descriptors are in a recent call. The glossary entry does a pretty good job as is, but I think that having an example will help people better understand what this actually looks like.

Need to verify in PR review whether this descriptor is legit. I had a hard time piecing things together from the available documentation I found.

@thunderbiscuit thanks for catching that. I updated the image.

Looks good to me. Having an example is great.

Very good to add in an example, a simple image can make a huge difference in someone understanding a concept.

• Minor suggestion would be to perhaps do the "Checksum for the descriptor" in another color as the grey and white could be tricky to differentiate for some. That said; white is on the front and grey at the tail end. So enough space between both to understand.
