Bring back scripts evaluation in TextPanel

[dprokop]

Fixes #26406

When html sanitization is disabled we need to process html against any inline script tag occurrences and eval those scripts to have an effect. React's dangerouslySetInnerHTML uses innerHTML which does not evaluate scripts: https://developer.mozilla.org/en-US/docs/Web/API/Element/innerHTML

@ryantxu I couldn't get the test for new logic to pass, any ideas? Seems like the parsed text is undefined in the test env, no idea why. Maybe some jsdom issue?

Alternatively we could use https://github.com/christo-pr/dangerously-set-html-content

ugg -- maybe we can take the opportunity to move script to an explicit script field?

Well, we could, but this will still be breaking change. And following this pattern we would have to provide style field too. I think with the Monaco editor having all the things in one editor is just fine.

for sure the approach in https://github.com/christo-pr/dangerously-set-html-content is better :)

const slotHtml = document.createRange().createContextualFragment(html)

yes, i'm testing this lib as we speak
