This pull request reduces the maximum number of Pulp content and API workers from 32 to 12 to prevent connection starvation on seed hosts. Feedback suggests updating the release note to accurately state that this issue affects hosts with 16 or more CPU threads, rather than 32, based on the worker calculation logic.

On seed hosts with more than 32 CPU threads, PULP_CONTENT_WORKERS and PULP_API_WORKERS were set to 32, which was causing the number of connections to the bundled Postgres instance to exceed the default max_connections. Reducing the maximum number of PULP_CONTENT_WORKERS and PULP_API_WORKERS will prevent Postgres from running out of connection slots.
