fix(mongodb): KubeBlocks 1.1 compatibility patch for MongoDB sharding

[gnolong]

Changes:

• Replace template functions in mongodb-shard-config.tpl and mongos-config.tpl.
• Remove hard-coded serviceVersion: 8.0.17 from sharding ComponentDefinitions so that Cluster serviceVersion 6.0.27 can match via ComponentVersion.

mongodb-shard-config.tpl and mongos-config.tpl now hard-code /data/mongodb, while the chart still exposes values.yaml:dataMountPath and the sharding ComponentDefinitions mount the data volume from that value. With a non-default dataMountPath, the rendered volumeMount moves but dbPath/log/tmp/pid paths in the config templates stay under /data/mongodb, so sharding pods no longer use the configured data volume path.
