Bootstrap VS Code Extension

[coliff]

I've been thinking about how great it would be to have an official Bootstrap VS Code extension. Some of the features I thought of that it could have:

• Autocomplete CSS classes - this one's a no-brainer to include. I know this is already possible with some other extensions like https://marketplace.visualstudio.com/items?itemName=Zignd.html-css-class-completion but would make sense for it to be included.
• Lightweight linting of HTML templates - Bootlint is deprecated now, but it used to be useful for catching HTML issues with Bootstrap component. Could be good to resurrect some of the rules from this.
• Autocomplete values for data-bs- HTML. e.g. typedata-bs-t and it'll suggest autocompleting to data-bs-toggle (I guess some of this is already available via AI extensions like GitHub Copilot, but not everyone has access to that)
• Warnings in console about using deprecated features / classes
• Automatically remove redundant CSS classes from templates, e.g. "col-9 col-md-9" is replaced with "col-9" - like https://marketplace.visualstudio.com/items?itemName=AgustinFornio.redundanty (great plugin by the way!)
• Autosuggesting updating older version CDN links. e.g. if you are loading https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css - it could show a note in the console that 5.3.3. is available (maybe could right click on it to auto-fix!)
• All the above could be configurable in the options.

I've done a little bit of maintenance of VS Code extensions before but I don't have enough experience/knowledge to build this myself from scratch. Maybe it could be a community effort? I'd be happy to help contribute :-)
