mongod log access API Atlas filename should be mongodb.gz instead of mongod.gz

Original Description

Using the current mongod.gz filename in Atlas logs request path parameter results in error below:

{"detail":"Invalid path parameter logName specified.","error":400,"errorCode":"INVALID_PATH_PARAMETER","parameters":(["logName"],"reason":"Bad Request"}

The document should be fixed to use mongodb.gz instead.
