Adding instructions on creating a folder in components library.

Wasn't sure where to upload the GIF, so here it is:

Merged, thank you very much!

This is not strictly necessary, because it's already explained in the libraries section (see last block of this section). But it helps to raise awareness of the possibility of grouping assets, so it's welcome.

Thank you @hirunatan ! I didn't even realize that the instructions already existed. Would it be better to move the GIF to the Libraries section and link to the libraries section on the components page?

No, I don't think so. It's good to put it in components section, because many people, like you, may read this section and don't realize that there is another one with all the assets.
