Several Doc improvement for whats_new

### Describe the issue linked to the documentation

I found some bugs or unclear areas that need further improvement in several versions of whats_new documentation.

### [v1.5.0](https://github.com/scikit-learn/scikit-learn/blob/main/doc/whats_new/v1.5.rst#version-150)

- "Deprecates `Y` in favor of `y` in the methods fit, transform and inverse_transform of: :class:`cross_decomposition.PLSRegression`, :class:`cross_decomposition.PLSCanonical`, :class:`cross_decomposition.CCA`, and :class:`cross_decomposition.PLSSVD`."[(link)](https://github.com/scikit-learn/scikit-learn/blob/main/doc/whats_new/v1.5.rst#modsklearncross_decomposition) However, class`cross_decomposition.PLSSVD` doesn‘t seem to have the `inverse_transform` method (refer to [class PLSSVD](https://scikit-learn.org/stable/modules/generated/sklearn.cross_decomposition.PLSSVD.html#sklearn.cross_decomposition.PLSSVD))
- "store_cv_values and cv_values_ are deprecated in favor of store_cv_results and cv_results_ in ~linear_model.RidgeCV and ~linear_model.RidgeClassifierCV."[(link)](https://github.com/scikit-learn/scikit-learn/blob/main/doc/whats_new/v1.5.rst#modsklearnlinear_model) I recommend to make it clear that the `store_cv_values` and `cv_values_` are Parameters (like the previous item), otherwise it will be misleading to know whether they are parameters or methods.

### [v1.4.0](https://github.com/scikit-learn/scikit-learn/blob/main/doc/whats_new/v1.4.rst)

- ":func:`sklearn.extmath.log_logistic` is deprecated and will be removed in 1.6. Use `-np.logaddexp(0, -x)` instead."[(link)](https://github.com/scikit-learn/scikit-learn/blob/main/doc/whats_new/v1.4.rst#modsklearnutils-1) The full qualified name of function `log_logistic` should be `sklearn.utils.extmath.log_logistic`.

### [v1.3.0](https://github.com/scikit-learn/scikit-learn/blob/main/doc/whats_new/v1.3.rst)

- "The parameter log_scale in the class :class:`model_selection.LearningCurveDisplay` has been deprecated in 1.3 and will be removed in 1.5."[(link)](https://github.com/scikit-learn/scikit-learn/blob/main/doc/whats_new/v1.3.rst) The deprecated parameter `log_scale` is actually a parameter of the `plot` method of the class `model_selection.LearningCurveDisplay`, not the class constructor. Refer to [this](https://github.com/scikit-learn/scikit-learn/pull/25120/commits/90a2bf46fd700d7e5c8279cddef95da2f519574d).

### Suggest a potential alternative/fix

### v1.5.0

- Deprecates `Y` in favor of `y` in the methods `fit`, `transform` and `inverse_transform` of: :class:`cross_decomposition.PLSRegression`, :class:`cross_decomposition.PLSCanonical`, and :class:`cross_decomposition.CCA`, and methods `fit` and `transform` of :class:`cross_decomposition.PLSSVD`.
- Parameters `store_cv_values` and `cv_values_` are deprecated in favor of `store_cv_results` and `cv_results_` in `~linear_model.RidgeCV` and `~linear_model.RidgeClassifierCV`.

### v1.4.0
- :func:`sklearn.utils.extmath.log_logistic` is deprecated and will be removed in 1.6. Use `-np.logaddexp(0, -x)` instead.

### v1.3.0
- The parameter `log_scale` in the method `plot` of class :class:`model_selection.LearningCurveDisplay` has been deprecated in 1.3 and will be removed in 1.5.

COMMENT:
Thanks for the suggestions. Checking these requires going back to the original pull request doing them to check how things could be improved. I wouldn't mind reviewing a pull request with some clarifications. But these are old changelogs and we don't have a priority to fix the issues you mentioned. So closing the issue. However, a pull request with the fixes is welcomed and feel free to ping me if you happen to open it.
