Review Comment:
   This is @valdar's preference. 
   
   However I see your point too. Damn. Why do I always see both sides to 
things!?!?
   
   The User is forced to either provide a _real_ value for the endpoint 
configuration or set its value in the header where it then takes precedence 
over the endpoint configuration. The default value is explicitly mentioned in 
the updated documentation and advises it _could_ lead to delivery failure.
   
   It's a difficult situation: The parameter is _required_, it is not optional; 
but _where_ it can be set (endpoint or per message) means Camel fails to deploy 
the Kamelet if the User does not set a value in the Configuration Options when 
marked as `required`. 
   
   We want to somehow impose configuration of a `chatId` on Users.
   
   I'll chat to @valdar again.. the imposition is something we want in RHOC but 
seems contrary to both the underlying Camel Telegram Component and your opinion.
