While working on #20999, I could notice that CalibrationDisplay has a name parameter while other displays have a estimator_name parameter. In #20999, I try to create a base class that manages, in the same manner, this parameter and it would be handy to have the same naming.

@thomasjpfan @lucyleeow Do you remember if there is a reason for choosing name instead of estimator_name in this display?
@adrinjalali If the change makes sense, I would submit a PR and it would be great to include before the release to avoid a deprecation cycle for this brand new display.
