Update list of allowed elements

[NullVoxPopuli]

Potentials lists we could use:

• https://www.npmjs.com/package/html-spec-tags?activeTab=readme

What we need:

• SVG Elements
• HTML Elements
• etc?

(or remove getTemplateLocals https://github.com/glimmerjs/glimmer-vm/issues/1550#issuecomment-1972012330 )

@NullVoxPopuli is this still needed?

Ya

babel template compilation plugin is not using getTemplateLocals anymore. so, maybe not needed? and just remove the whole list? basically, now, everything is a html element, except if it has a js local. How does it work for non-strict mode?
