Missing doc and sample dag for ExasolToS3Operator

### What do you see as an issue? The operator ``ExasolToS3Operator`` is missing a sample dag and documentation which would benefit users. In order to test the sample dag you need to have an [Exasol](https://www.exasol.com/) account which requires a credit card (even with the free trial). If someone has an Exasol account and is willing to create a sample dag and test it, that would be a good bonus for the community. ### Solving the problem Create a sample dag and test it Create the documentation associated with it ### Anything else _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md)
