Docs: rename form checks page to "Checks / radios" (#31090)

* Docs: rename form checks page to "Checks / radios"

it's not immediately obvious that "checks" includes information about both checkboxes and radio buttons. while "checks / radios" is also still not perfect (as honestly even I didn't quite grok that "checks" meant checkboxes), it should make it slightly more obvious nonetheless

 ### Buttons
 
-- The checkbox/radio toggle is removed from the button plugin in favour of a CSS only solution, which is documented in the [form checks]({{< docsref "/forms/checks#toggle-buttons" >}}) docs. The `.btn-check` class can be added to inputs, any label with `.btn` and modifier class can be used to theme the labels. [See #30650](https://github.com/twbs/bootstrap/pull/30650).
