Set iframe height for Vue and Svelte demos in the docs

[sequba]

Context

This PR:

• sets the height of the iframes to make them show the entire demos
• removes the invalid sandbox flag 'allow-autoplay' from all demos

Other notes:

• It is possible to force running these demos in a regular codesandbox (instead of devbox) by setting "template": "static" in sandbox.config.json. But then, the demo would not run. I guess some bundlers are not supported in regular codesandboxes, and there is a reason these demos are automatically converted to devboxes.
• Embedding devboxes is a beta feature and configuring the layout of the demo is currently impossible contrary to regular sandboxes. Even the official example of a devbox doesn't seem to work as expected (it doesn't display a file by default).
• I tried different undocumented URL params, but nothing works for devboxes
• I tried different configurations in sandbox.config.json, but nothing works for devboxes
• If codesandbox didn't fix these issues with embedded devboxes, I recommend moving away from codesandbox and trying another service to embed the demos in the documentation
