Add keywords to the docs

[clizbe]

Description

Our strategy of keeping everything general might make it hard for analysts to find the specific concept they're looking for.
What might help is adding keywords/tags to the docs that help when searching.

For instance, in the storage section we might add something with words like "battery," "batteries," etc.
Or once we have MIMO, tag it with "industry," "industrial processes."

Not sure what's a nice/clean way to do this.

Motivation

If someone is checking if Tulipa can do X, and they just search for X, they might not find it explicitly and think it therefore doesn't exist.

Also, once someone is using Tulipa, it might help them find the way of doing what they want, without knowing the general concept of how to model it (like MIMO or Group Constraints). We can also help a bit with this through tutorials, but I think these tags would help too.
