Wrong description for tasks.*.dir in JSON Schema

[JanPokorny]

Small bug report: In the JSON Schema for mise.toml, tasks.*.dir has a wrong description -- default is the config root, not cwd:

"dir": {
  "default": "{{ config_root }}",
  "description": "directory to run script in, default is current working directory",
  "type": "string"
},
