[IntelliSense] add support for sycamore rust DSL

[mkmik]

https://sycamore-rs.netlify.app/docs/v0.8/basics/view

The sycamore rust crate allows you to write DOM elements using a DSL embedded in a rust macro.

Elements declared in that macro can include attributes, and in particular interest for the tailwind intellisense plugin, is the class attribute:

view! { cx,
    // A simple div
    div {}
    // A div with a class
    div(class="foo")
    // An empty paragraph
    p {}
    // Custom elements!
    my-custom-element {}
}

I noticed that among the "js" languages you already support non-JS languages:

export const jsLanguages = [
  'javascript',
  'javascriptreact',
  'reason',
  'rescript',
  'typescript',
  'typescriptreact',
  'glimmer-js',
  'glimmer-ts',
]

Would it make sense to add support sycamore ?

Or is this something that can be approximated with tailwindCSS.experimental.classRegex ?
