…ranslator (#26028)

## Summary & Motivation

Mark DagsterTableauTranslator.get_asset_key as deprecated. To be removed
in 1.10.

This PR stack will be merged after #25941 lands, so that
`replace_attributes()` can be called as
`AssetSpec().replace_attributes()`

## Changelog

[dagster-tableau] `DagsterTableauTranslator.get_asset_key` is deprecated
in favor of `DagsterTableauTranslator.get_asset_spec().key`
