`maxlength` for `TextArea` tag

[go-inoue]

Is your feature request related to a problem? Please describe.

• I want to have a input length limit for TextArea tag.

Describe the solution you'd like

• Having a parameter maxlength as in HTML for TextArea tag.

Describe alternatives you've considered

• This can be done with JavaScript, but I wasn't sure how to include a custom script within Label Studio.

Additional context

• This feature is useful when you want to limit the max length of user input, for example, when you annotate for summarization.

Hey @go-inoue ! Thank you so much for your feedback!

This would be a nice feature request — I'll flag it internally and please feel free to follow up if you have any questions.

I have implemented the single-char-wise max length validation functionality to my label-studio-frontend fork as follows. Please feel free to cherry-pick if you'd like it. (However, my impl may be different from LabelStudio's policy, because I'm unfamiliar with JS, React and Mobx...)
