DatePicker - multiple validators should render separate helper texts

Is this a new component or an extension of an existing one?
DatePicker

Describe the feature
Currently DatePicker renders only a single HelperText for errors, regardless of how many validators may be passed in. If multiple validators return a error string, each string is added to a single string state with an escaped newline between them, resulting in a single helper text item (with the intent being each validator string will be separated by a new line, but it doesn't seem like that is happening for me, i.e. it all gets rendered as a single line).

Instead we should create a new HelperText item for each validator that returns an error string so as to be less confusing if multiple errors are being rendered.

CC @andrew-ronaldson is this the intended behavior, or is there something else in mind for multiple validators returning error text?

Are there visuals for this feature? If applicable, please include examples for each state and for varying widths
Include screenshots or links to Marvel or other mockups.

Any other information?

Start by locating the DatePicker entry point and its current HelperText rendering and validator handling. Confirm how multiple validator error strings are represented, then make the completed behavior one separate HelperText item per returned error string and verify the DatePicker behavior.
