Add Sword/Shield encounters (Part 8: SWSH DLC Max Raids - Final Part!)

[jemarq04]

Change description

The final continuation of PR #1550, #1564, #1577, #1581, #1600, #1604, #1610, addressing issue #1459. This PR adds all the max raid encounters in the Isle of Armor and Crown Tundra zones, loaded from Bulbapedia webpages using a web scraping script. If a pokemon was encountered in its Gigantamax form, I marked them as such.

A new location area was added for each max den available in a given wild area location. They are named using Bulbapedia's naming scheme, as I used those pages primarily to add the encounters. A couple minor issues fixed with location prose.

This is the final PR adding Sword/Shield encounters! I'll have to figure out where I'll focus efforts next (likely Legends Arceus), but for now I can finally say: Closes #1459.
