Prevent prop s keys to be transformed in render array keys with # in StoriesSyntaxConverter

Thanks you so much Kensae, your solution is very pragmatic, targeting exactly where the issue here in SDC prop conversion.

However, we are currently facing a similar issue in UI Example module: ✨ Support Single directory components Active and I would address to address both:

• in a more generic way, because the root cause is the wrong sue of render children by SDC
• in a similar way in both module

So, I let this in review state for now.

Do we need tests mixing #-prefixed properties and not already #-prefix properties?

Data:

       '#type' => 'component',
        'component' => 'ui_suite_daisyui:card',
        '#slots' => []

Expected:

        '#type' => 'component',
        '#component' => 'ui_suite_daisyui:card',
        '#slots' => []

Data:

       'type' => 'component',
        'component' => 'ui_suite_daisyui:card',
        '#slots' => []

Expected:

        '#type' => 'component',
        '#component' => 'ui_suite_daisyui:card',
        '#slots' => []

Data:

       '#type' => 'html_tag',
        'tag' => 'p',
        'anything' => []

Expected:

       '#type' => 'html_tag',
        '#tag' => 'p',
        'anything' => []

Data:

       '#type' => 'html_tag',
        'tag' => 'p',
        'anything' => []

Expected:

       '#type' => 'html_tag',
        '#tag' => 'p',
        'anything' => []

And also, some tests about #theme;: layout which is the reason why we started this work.

MR updated.
