add Elemental Instinct Barbarian Subclass

[cgahr]

I added the elemental instinct barbarian subclass.

The wording is identical to https://2e.aonprd.com/Instincts.aspx, however, I slightly changed the sentence containing the link to the table to make it grammatically correct.

• [x] The only remaining issue is that the table containing the elemental instincts does not link correctly. npm run serve:dev shows the table, however, if I hover over the link, it is not shown as a popup. Can you help me with that?

You have not added the table to the Tables page, that's why its not shown as a pop-up.

To avoid double data-entry, move the table to that page and use the statblock entry in the class itself. CTRL + F the repo for examples.

Thanks for the hint! Now everything should work correctly.

However, I have nowhere used the statblock entry.

Tag the subclass in Elemental Evolution and Elemental Explosion feats and we are fully finished with this conversion.
