fix(icon): codepen demo issue (#9780)

* The icon demo with the SVG files from URLs was not working for the codepen checkout, because it seems like the "inlined" SVG has some escaping issues (especially when being wrapped inside of single qoutes inside of HTML).

* Moving the SVG template into the Script (as same as for the decoded SVG) does fix the issue, and is also makes the demo look better.

Fixes #9561.
