[I] Configuring SequentialExecutor results in very non-obvious error [airflow]
dstandish opened a new issue, #48765:
URL: https://github.com/apache/airflow/issues/48765
### Body
If sequential executor is configured, an unhelpful error is emitted
It should make it clear that SequentialExecutor is disabled.
Maybe it should even "upgrade" to local executor?

To repro, set `AIRFLOW__CORE__EXECUTOR=SequentialExecutor` and run `airflow db check`

Oh this is made worse by the fact that the default config file from 2.x has "SequentialExecutor" stamped in it

@vikramkoka I think the mapping for the `SequentialExecutor` was missed. I have added the change in this [PR 48800](https://github.com/apache/airflow/pull/48800)

I ran into this as part of beta4 and expected "config update" to take care of this.
