Reference Issues/PRs

This PR is part of #11000 .

What does this implement/fix? Explain your changes.

This MR confirms that SparsePCA and MiniBatchSparsePCA transformers preserve numpy.float32. Due to #22002 sparse PCA come to preserve numpy.float32. So tests to confirm preserving numpy.float32 are added.

Any other comments?

I used #20155 as references to make this.
