Use a `.cspell.json` repo config file instead of `.vscode/settings.json`

[josecelano]

We have the cspell word list in the IDE settings. I would move it to a .cspell.json file in the root dir:

{
  "version": "0.2",
  "language": "en",
  "ignorePaths": [
    ".vscode",
    "**/.git/**",
    "**/vscode-extension/**",
    "megalinter"
  ],
  "words": [
    "byteorder",
    "hasher",
    "leechers",
    "nanos",
    "rngs",
    "Seedable",
    "thiserror",
    "torrust",
    "typenum"
  ]
}
