Add ember-template-lint-plugin-tailwindcss plugin to ember-template-lint

I think it will be great to add https://gitlab.com/michal-bryxi-oss/ember-template-lint-plugin-tailwindcss plugin to this repo

Let's see. There is a prettier-plugin-tailwindcss that does similar things (IIRC only sorting, not formatting).

The advantage of using prettier-plugin-tailwindcss is:

• It's officially developed by the folks from Tailwind
• It Will support all the tailwind classes; While ember-template-lint-plugin-tailwindcss will play a catchup game unless it can plug into prettier-plugin-tailwindcss code directly
• Using the official plugin would also align us with the rest of the world.

On the other hand when using prettier-plugin-tailwindcss:

• The user would need to use prettier within the templates. I guess through ember-template-lint-plugin-prettier? Can that be done automagically through ember-template-lint config?
• There is way more flexibility in ember-template-lint-plugin-tailwindcss.

So I tried to make a little sandbox app that uses the official prettier-plugin-tailwindcss and as advertised:

• It has minimum features / configuration options.
• Attributes with a lot of class attributes will be really long as it does not handle any sort of line wrapping.
• Also enforced linebreaks are not a thing
• I don't think there is a warning against concatenated class attributes, which is a good security feature to protect oneself from writing code that will wipe out said classes on build

But it's still the official one and comes with all the niceties of official plugin:

• Knows all the classess and knows how to sort them
• Is always(tm) up to date with the latest development

So I think if we want to adopt the unofficial ember-template-lint-plugin-tailwindcss, then we should patch it so that it plugs into the official prettier-plugin-tailwindcss sorting mechanism.

But I don't have a strong opinion on which one should we use afterall.
