Legacy Template block is always rendered full width

[Aljullu]

The templates we have been creating as part of the Store Editing Templates v1 project render the Legacy Template block directly into the content, that causes it to take all the available wide space.

I took a look at how that's done in other templates, and they seem to use a Group block with the attribute {"layout":{"inherit":true}}, that way it gets the correct width from the theme.

Some themes also add custom class names to that Group block, but given that this depends on the theme, that's not something we can implement on our end.

This issue is about updating the templates under /templates/block-templates/ and replace:

<!-- wp:woocommerce/legacy-template {"template":"single-product"} /-->

with:

<!-- wp:group {"layout":{"inherit":true}} -->
<div class="wp-block-group"><!-- wp:woocommerce/legacy-template {"template":"single-product"} /--></div>
<!-- /wp:group -->
