        Resolver specific configuration keys can be found here: https://maven.apache.org/resolver/configuration.html

        This is to work around an issue where Maven builds in Github Actions would randomly fail.
        There is some evidence that points at Azure networking as the root cause where it closes idle connections (silently) after 4 minutes.
        Maven would then sometimes reuse an "old" connection from its connection pool and would encounter issues due to these connection closures.
        This patch changes the TTL for the connections to a lower value than 4 minutes (240s), the default is 300s (5min).

        There are two properties here because sometimes in November 2023 the name was changed.
        The new name will only take effect as of Maven 4, but it doesn't hurt to add it here already, therefore, we just add both properties here.
        https://issues.apache.org/jira/browse/MRESOLVER-440

        <!--
        This is an option we can experiment with in the future. Settings this to false will result in no connection
        pooling, which should help to avoid stale/long-lasting connections which can become inactive and be killed by
        the Azure networking.
