Support pattern field on Textarea

[peter-dick-aracom]

Having a set of regex rules defined as constants and directly set in OnyxInput using pattern field is very convenient and would be great to have the Textarea to be able to support the very same, without requiring boilerplate around it to achieve the same.

Hi @arapd,
interesting idea. Do you have some examples/suggestions for common regexes?

[peter-dick-aracom]

Those always depend on the usecase. E.g. mandatory inputs, which contain at least one non-whitespace character: /.*\S.*/

@JoCa96 I assume the change would not require bigger effort to implement. Is it possible to have this implemented? Because our product requires this feature and we try to minimize creating workaround / extensions, to avoid unnecessary refactorings in the future.
