use Spyglass for datapack linting

[TheAfroOfDoom]

we can rely on Spyglass now that v4 is out once CLI linting is implemented

we get a little bit of linting in vscode with [Datapack Helper Plus](https://marketplace.visualstudio.com/items?itemName=SPGoding.datapack-language-server), but DHP is pretty buggy and we shouldn't rely on it to actually lint, I don't think. instead we should probably write a script in-house to do stuff before we run the test server: we'd want the linting script to ensure to run on specific files (`.mcfunction`, `.json`, etc.) and check that: - they have a new-line at the end of the file - all (most? idk) strings use single quotes `'` instead of `"` - all SNBT has the correct white space; e.g. - `{Tags:["tag1","tag2"]}` wrong ❌ - `{ Tags: ["tag1", "tag2"] }` correct ✔️ we'll probably want more rules than above but that's a decent start.

adding linting ensures our files have consistent styling (like SNBT whitespace)

---

~we'd also want to add this script to the datapack.yml/resourcepack.yml workflows so that we run the linting script before we run the test server~ done

linting rule idea: ensure every instance of # TODO is in the correct format:

• has an associated issue number: # TODO(xx): blah ✔️ , # TODO blah ❌
• associated issue number exists (how to determine this? github API?)
• ends with a colon: # TODO(xx): blah ✔️ , # TODO(xx) blah ❌

infrastructure for this was added in a50e084 (#62)

should be pretty easy now to add rules for the things mentioned above

see 787cd85 (#62)
