chore: rename Adapter::getContainer() call to getContext()

Upstream removed Adapter::getContainer() in favor of a single
public reader Adapter::getContext(): Container that returns the
container for the current execution context (per-request inside
a request, global outside one). Migration is a one-line rename.

The only call site was the installer's bootstrap, which runs at
boot and therefore receives the global container — same semantics
as before.
