Subject: [PATCH] breaking: deprecate `context="module"` in favor of `module`
 (#12948)

* breaking: deprecate `context="module"` in favor of `module`

Also reserve a few attributes, which we may or may not use in the future

closes #12637

* fix tests

* one more

* add svelte package to the root so eslint and prettier can use it

* tweak messages

* warn on unknown attributes

* regenerate

---------

+A `<script>` tag with a `module` attribute runs once when the module first evaluates, rather than for each component instance. Values declared in this block are accessible from a regular `<script>` (and the component markup) but not vice versa.
 
 You can `export` bindings from this block, and they will become exports of the compiled module.
 
 You cannot `export default`, since the default export is the component itself.
