Fixes #2474

What does this implement/fix? Explain your changes.

This pull request fixes the incorrect links in the Overview Estimator page in the documentations.

The issue was that the all_estimators function from the aeon.utils.discovery module wasn't providing correct path to those classes mentioned in #2474 (comment)

It turned out, that the those classes generally don't have a **underscore** in front of their file names. It's because they're not part of a sub module.
For example, the DummyClassifier actual is a part of the classification module, but it's directly inside that, unlike the rest of the modules.

To fix this, I thought of few ways, such as handling these cases in the code itself. However, the best was I think is simply adding a underscore in front of those files and also fixing the imports after that.

Following files will be fixed:

• DummyClassifier
• DummyClusterer
• SeriesSearch
• QuerySearch
• RocketGPU

The problem with the last class is that it's documentation doesn't exist whatsoever.
After looking into the codebase, it turns out that the folder structure is a bit different from the rest of the classes, and maybe because of that Sphinx is not able to generate it's documentation.

One fix would be changing the folder structure, I'm not sure though.
Let me know what I can do.

Thank you!
