   Unable to use topicPattern when topic's name contain dots "."
   
   ### Affected Version
   
   32.0.0
   
   ### Description
   
   When trying to ingest from multiple kafka topics that contain "." character 
in their names (Example: abc.context.topic-name1) I get the following error: No 
partitions found for topics that match given pattern
   
   I have tried changing the input to multiple formats but I always get errors:
   abc.context.topic-(name1|name2)
   abc.context.topic-name1|abc.context.topic-name2
   abc\\.context\\.topic-(name1|name2)
   abc\\.context\\.topic-name1|abc\\.context\\.topic-name2
   abc.context.topic-.*
   abc\\.context\\.topic-.*
   
   When I try inputing the same names but in the topic instead of topicPattern 
they work normally.
   
   It seems to be a bug in the pattern matching when topic names have special 
characters.
