The section was only partially updated when `'always'` became the default: it still showed the `'emptyOnly'` configuration and the parent traversal example before the explanation of the default. Show the default behavior first and move `'emptyOnly'` to a legacy note. Also drop the "(Experimental)" tag from `shouldDestroyInjector`, which is now stable.

What is the current behavior?
Issue Number: N/A
The "Control parameter inheritance" section was updated when #68256 changed the default
paramsInheritanceStrategyto'always', but the example still leads with the'emptyOnly'configuration and the parent route traversal.This makes the default behavior less clear, since the first example a reader sees is for the legacy option rather than the default.
The
RouteReuseStrategytable also still marksshouldDestroyInjectoras "(Experimental)", even though the feature was stabilized in #70443.What is the new behavior?
The parameter inheritance section now starts with the default
'always'behavior, showing aCustomercomponent reading the inherited parameters directly.The
'emptyOnly'configuration is then documented as the legacy option, along with the parent traversal example.The "(Experimental)" label is also removed from the
shouldDestroyInjectorrow.Does this PR introduce a breaking change?
