[REM] website_slides: legacy field_float_rating widget

We remove the `field_float_rating` widget in this commit
as is was not used anymore. Its use was dropped at an
earlier PR, however without deleting it.

For reference, we mention here the PRs in which the widget
was firstly introduced and when in was made redundant.
- introduced: #33255
- removed: #55698

closes odoo/odoo#99983
