chore(deps): update to react 19

[matthewgallo]

Closes #6553

Adds support for React 19.

A side effect I found from the removal of prop types is the fact that none of the warnings/errors we emit from our custom prop validations are added anymore. This means that any test we previously had to ensure errors/warnings are logged now fail. As React is turning to TypeScript now for type checking, I've removed any tests that checked our old way with custom prop type validations.

Findings:

• Not able to customize story labels, toolbar in storybook. Maybe this is something storybook is currently working on since the release of React 19 is so new at this point. For example, in packages/core/.storybook/manager.js, rendering anything other than a string for sidebar.renderLabel fails. However, this is now supported with the following storybook addon.
• Issue with @carbon/react Tabs component, possibly because the version of @carbon/react being used doesn't include React 19 support yet. If this is the case, we'll need to wait until a version supporting React 19 has been published. Resolved with adding [email protected] to our resolutions

What did you change?

How did you test and verify your work?

Confirmed all tests pass, components in storybook render as expected
