chore: bump major dependencies VSCODE-787

[alenakhineika]

Description

• Upgraded major deps, including ESLint@^10 that required a migration to a new flat-config format.
  • Provided a temporary adopter for @mongodb-js/eslint-plugin-devtools.
  • Refactored the codebase so it passes the new rules and updated APIs.
• Refreshed transitive dependencies via overrides.
• Added unused artifacts to vscodeignore:
  • Codicon artifacts (~1.2 MB) - the extension only loads codicon.css + codicon.ttf the rest are package documentation.
  • Monaco artifacts - css.worker (1 MB) + html.worker (693 KB) - the data-browsing webview only uses the typescript language (defaultLanguage="typescript"), so these are never fetched.
