Signed-off-by: Peter Staar <taa@zurich.ibm.com>

* reformatted code of html backend

Signed-off-by: Peter Staar <taa@zurich.ibm.com>

* test(html): add more info if a test case fails

Signed-off-by: Cesar Berrospi Ramis <75900930+ceberam@users.noreply.github.com>

* refactor(html): put parsed item in body if doc has no header

In case an HTML does not have any header tag, all parsed items are placed in
DoclingDocument's body content layer.
HTML paragraphs ('p' tags) are parsed as text items with paragraph label.
Update test ground truth accoring to the changes above.

* chore: set TextItem label to 'text' instead of 'paragraph'
