Fix profiler service deprecation by using non-deprecated internal id

Accessing the "profiler" service directly from the container triggers a
deprecation since symfony/framework-bundle 5.4: "Accessing the "profiler"
service directly from the container is deprecated, use dependency
injection instead."

The public "profiler" id is a deprecated alias that calls
trigger_deprecation() before delegating to the real, non-deprecated
private definition ".container.private.profiler". Prefer the internal id
and fall back to "profiler" for older/edge configs where the alias does
not exist. This avoids the deprecation on every container path (raw or
test container) across Symfony 5.4 to 8.0.

Closes #212
