Add modalities tag to blog

[mishig25]

Add 4 modalities tags (nlp, speech, vision, rl) (technically, I guess, it is 3 modalities + rl) & tag relevant blog posts
(as requested by @patrickvonplaten)

Awesome thanks a lot!

can we use the same modalities names as in https://github.com/huggingface/huggingface_hub/blob/a217a7e04d4c6785e36fe193ee2576be95815157/js/src/lib/interfaces/Types.ts#L62-L67 for consistency? (and add missing ones there if needed)

More generally let's try to promote naming consistency accross the huggingface platform, going forward :)

do we still want to merge this BTW? 🙏

[mishig25]

I've added the modalities tags to newer blog posts as well.

Implemented naming consistency based on below const:

export const MODALITIES = [
	"nlp",
	"audio",
	"cv",
	"other",
] as const;

For reinforcement learning (which does not exist in const MODALITIES), I've chose rl. wdyt @simoninithomas ?

[julien-c]

you can maybe add rl to modalities now, or does it not make sense @osanseviero?

[mishig25]

Here is the hub-docs PR in case we want to add rl to modalities

[osanseviero]

I think you can merge rl_modality to this branch and then merge all into main.
