id prop passed to TextArea is taking dynamic values in rendered HTML

[lpatel-eightfold]

The id prop passed to TextArea component, should ideally remain unchanged in the final HTML. But instead a number gets appended to the end of the passed id.
The issue can be reproduced on the storybook site as well:

@lpatel-eightfold noted, in the meantime if your goal is to use the id for test purposes, please use data-test-id instead. If using for css, consider using the classNames prop.
