Prevent VSCode CSpell from checking all code files

The VSCode CSpell extension (aka "code-spell-checker") 4.0.19 release
(2024-11-19) changed the `enabledFileTypes` setting default to make it
"easier to extend." The change also made CSpell check all words in all
code files, resulting in a noticeable increase in spell check errors
reported by the extension.

The `"cSpell.enabledFileTypes": { "*": false }` setting suggested in
streetsidesoftware/vscode-spell-checker#3800 does not work correctly
(streetsidesoftware/vscode-spell-checker#3836). Languages must be
configured individually.

This commit will update `cspell.json` to configure common code languages.

- Ruby is disabled to avoid checking commented-out lines in Brewfiles.
- Excluding HTML from the `languageSettings` array will allow CSpell to
  check not only comments, but also prose elements like `<p>`. It's not
  clear how to also check prose elements in JavaScript components.
- When checking Astro, Vue, and other component languages, CSpell should
  check HTML, CSS, and JS comments. All may occur in a single file.
- When checking shell, CSpell should ignore array length references
  (in Bash, the length of an array can be read with `${#ARRAY_NAME}`).
- CSpell still seems to be spell checking keys in VSCode `settings.json`
  even though JSONC is correctly configured to only check comments.
