feat(spotless): prettier json

[leagris]

Normalizes json files matching:

• src/**/mcmod.info
• src/**/*.json
• src/**/*.mcmeta

Processes only changed files from origin/master.

Normalizations:

• Indent with 2 spaces
• Preserves collapsed objects/arrays on same line when it does not exceed 100 chars
• Uses unix newline LF
• Ends file with a newline character

Note for reviewers:

To test this config:

• Checkout this PR feat(spotless): prettier json #308 on the ExampleMod1.7.10 project (with GitHub CLI):

  gh pr checkout 308

• Modify or add some JSON files

  # Forces a genuine change to the file so it will be handled by spotless
  printf \\n >> src/main/resources/mcmod.info 
  
  # Create a pack.mcmeta file that will be formatted by spotless
  cat > src/main/pack.mcmeta <<'JSON'
  {"pack": {
  "pack_format": 1, "description": "ExampleMod Resource Pack"}
  }
  JSON
  # add it to index without tracking
  git add -N src/main/pack.mcmeta

• Run Spotless for the json category:

  ./gradlew spotlessJsonApply -Pgtnh.settings.blowdryerTag=LOCAL

  Setting the property blowdryerTag=LOCAL tells Blowdryer to use the local gtnhShared directory for the spotless configuration files.

• Then inspect the changes with:

  git diff

• Optionally restore the repository with:

  git reset src && git restore src && git clean -f src
