fix: podcast episode preview content

Checklist:

• I have read freeCodeCamp's contribution guidelines.
• My pull request has a descriptive title (not a vague title like Update index.md)

Removed HTML widget because of maxLines property did not work as expected if the content contains elements like line breaks or other block-level elements that can break the line. That's why I added the text widget, by parsing the body of the description used as textcontent in the widget. By using the text widget we can see max lines 3

Closes #1175

Links won't be clickable anymore, we should probably use the HTML widget, despite the text being longer than 3 lines.

ok, the link is only clickable if it has 'href" tag only, some of the links are not in href tag.

I think that's fine as this is just a preview of the what the episode has to offer. The clickable links and more details can be seen in the respective episode view.

The analyzer has reported some errors in your code. You can view them by running flutter analyze. Also where are you making these changes from as they seem to be somehow bypassing the pre-commit check.
