[docstring] Replace inexistent object DltDagsterResource by `Dagste…

…rDltResource` (#26518)

## Summary & Motivation

While going through the [API reference docs
](https://docs.dagster.io/_apidocs/libraries/dagster-embedded-elt#dlt-dagster-embedded-elt-dlt)
I found code errors and it didn't match [the code snippet from the
integration page](https://dagster.io/integrations/dagster-dlt).

Searching the codebase for `dltdagster`, results were only found for
this file while `dagsterdlt` had results in ~13 files.

I modified the code snippet found in the docstring.

## How I Tested These Changes

No test were conducted.
