Related to sktime/sktime#9497.

scikit-learn has updated how they display parameters in the HTML display of estimators. scikit-base should be updated to match this, since scikit-base has its own html repr code.

Plan:

• In the html repr module, replace the <pre> text block with a structured parameter table using get_params(deep=False)
• Link parameter names to documentation via existing doc link infrastructure
• Update CSS to style the table consistently

I will be working on this and submitting a PR.
