HADOOP-18159. Bump cos_api-bundle to 5.6.69 to update public-suffix-list.txt (#4444)

Bump cos_api-bundle to 5.6.69

All copies of httpclient, including shaded ones in libraries used
by the s3a, gs and cos cloud connectors, turn out to load their
TLD list from the same resource mozilla/public-suffix-list.txt 

Updating the hadoop-cos dependency ensures that its version 
of public-suffix-list.txt is up to date -and so the s3a connector 
able to talk to s3 resources if the cos-api-bundle JAR is where
the resource is loaded from.
