fix(html): include innerHTML content in rendered asset tags

[faultyserver]

Summary

I was trying to implement an HtmlRspackPlugin addition using the alterAssetTags hook, and for my use case I needed to set innerHTML on the generated tag (to get something like <script>console.log("Hello")</script>). After a lot of confusion about why things weren't showing up as I expected and instead got empty tags, I went to look at the implementation and found that HtmlPluginTag was always setting children to an empty vector.

This PR fixes that to render the innerHTML property of the tag there as a plain Text node if it's present. I also tried to add an end to end test for this, but wasn't able to get them running locally immediately, so hopefully CI will indicate if it's correct, otherwise I'll get them set up and running to try it out.
