Option to display y axis title vertically

### Feature Proposal

Thank you for creating such a useful library! So far, the development experience has been amazing!

Today, I would like to request a feature where I can add an option to show y axis title vertically. Some languages such as Japanese and Chinese can be written vertically and in some cases it is more desired to do so.

This is an example of a Japanese text shown horizontally as a y axis title.

I would like to show this title vertically, just like `text-orientation: upright;` does for css.

Having another option on https://www.chartjs.org/docs/latest/api/interfaces/TitleOptions.html might be nice.

Thanks for your time! and looking forward to see if this is possible!

### Possible Implementation

I'm not an expert on this, but maybe this might help?
