Update Cumulocity log management documentation to fix various paths and typos. The following items were corrected:

• Fix path to software management log files in the logging example
• Remove c8y_LogRequest from example as the log files are not currently used

The doc change of c8y-log-plugin.toml is very nice, thanks for catching them. However, the change of the c8y-configuration-management doc must be reverted. Therefore, I block merging.
