Improve documentation on generating train/valid/test datasets

[kasra-hosseini]

• Document some of the methods that we have tried in our experiments so far to generate negative examples.
• Add experiments/case-studies so far

Related docs:

• https://github.com/LinkedPasts/LaNC-workshop/tree/main/deezymatch
• @mcollardanuy wrote: "We already have a "Tips / Suggestions on DeezyMatch functionalities" section (https://github.com/Living-with-machines/DeezyMatch#tips--suggestions-on-deezymatch-functionalities) that we could then move to that separate document"

@mcollardanuy I just created this branch feature/108-negative-examples from develop to address this issue.

We do have some documentation/tutorials on this:

Ah great, thanks! I will also collect the scripts we have to create the different string pairs datasets, maybe we can unify them somehow. I'll work on this on Friday or next week.

Great, thanks! Whenever you have time...I am also happy to help.

I think it would be good to have a separate directory (maybe in DeezyMatch/examples? but, of course, please feel free to create a new directory if needed) where we collect all those scripts and tutorials/docs regarding experiments/use-cases. We can then link that directory from the README.
