fix: set use_instructions to True in models using prompts

[dbuades]

As a follow up to embeddings-benchmark/mteb#1616, this PR updates the corresponding model_meta.json values for those specific models and revisions.

Note that I did not modify the values for certain Voyage models, as they show up as “no revision available” and lack a model_meta.json file altogether.
