Annotations on iOS File logging config example are incorrect

https://docs.couchbase.com/couchbase-lite/3.2/swift/troubleshooting-logs.html#eg-file-log

The annotations 2 and 4 are incorrect.
The code at annotation 2 is setting the log format to plain text, which disables binary logging (binary logging is the default).
The code at annotation 4 is setting the global LogFileConfiguration to use the config just created, which will cause the file logging to be enabled.

Also, we generally discourage text logging, and try to encourage customers to use binary logging. So I would recommend changing the code at annotation 2 to:
code:swift
config.usePlainText = false
code

The description could then be something like:
Set the logging format to binary by disabling text logging. This is the default, and is only shown here for reference.
