Spring Modulith with MongoDB requires TransactionManager even with transactions disabled

[janpetryk]

spring:
  modulith:
    events:
      republish-outstanding-events-on-restart: true
      externalization:
        enabled: true
      mongodb:
        transaction-management:
          enabled: false

Expected Behavior
The application should start successfully since transactions are explicitly disabled.

Actual Behavior
Application fails to start with:

***************************
APPLICATION FAILED TO START
***************************
Description:
A component required a bean of type 'org.springframework.transaction.TransactionManager' that could not be found.

Environment

Spring Boot: 3.2.2
Spring Modulith: 1.3.1
MongoDB

Suggestion
Add support for running without a TransactionManager when transactions are disabled via properties, eliminating the need for custom configuration.
