Add hyperscript support, enable 'key: value' style js code

[ntilwalli]

This is a simple regex update to enable autocomplete support for hyperscript. Previously only class="foo" or className="foo", would activate the autocomplete, with this PR class:"foo", class: "foo", className:"foo" and className: "foo" also activate autocomplete.

Hey @ntilwalli. Thank you, but I think for now I'd like to keep the built-in support to things that look like HTML class attributes (i.e. they use = to separate the key and value).

You could perhaps enable support for this syntax by using the experimental.classRegex setting. Here's a basic example:

"tailwindCSS.experimental.classRegex": [
  "\\sclass:\\s*\"([^\"]*)\""
]
