Andrea Giammarchi a1281d1331 Fix #1326 - Allow <script type="py"> tag to work as <py-script> (#1396)
The goal of this MR is to unobtrusively allow the usage of `<script type="py">`, `<script type="pyscript">` or `<script type="py-script">` tags instead of `<py-script>` for all those case where the layout in custom elements get parsed and breaks users' expectations (including our SVG based tests).
