Make error message uniform when calling `get_feature_names_out` before `fit`

While working #24838, we found out that we are not consistent with the error type and message when calling `get_feature_names_out` before `fit`.

From @jpangas:
> Here is the updated list of the estimators that raise inconsistent errors when `get_feature_names_out` is called before `fit`. Currently, these estimators have been whitelisted. Before we submit any PR for a particular estimator, we can remove the estimator from the list and run the test in #25223 to check if the code we submitted has raised the correct `NotFittedError`.

> Remember to add your estimator and PR in the same change log entry in `v1.3.rst` introduced in #25294.
Please link the PRs you'll make with this issue so that I can update this list for all of us to know which estimators have been worked on:

</details>

I assume that the most adequate error should be a `NotFittedError` asking to fit the estimator.

@scikit-learn/core-devs WDYT?

COMMENT:
@jpangas I was going through the list of estimators in https://github.com/scikit-learn/scikit-learn/issues/24916#issuecomment-1368540781 and I think need to include these ones as well: https://github.com/scikit-learn/scikit-learn/blob/bf03a6354670414695ef483de8187135aeec6cbd/sklearn/tests/test_common.py#L489-L490

I'll make a PR for this.
