carbon-components-react Change titleText in Dropdown to be optional

[samrobbins85]

Please fill in this template.

• Use a meaningful title for the pull request. Include the name of the package modified.
• Test the change in your own code. (Compile and run.)
• Add or edit tests to reflect the change.
• Follow the advice from the readme.
• Avoid common mistakes.
• Run npm test <package to test>.

Select one of these and delete the others:

If changing an existing definition:

• Provide a URL to documentation or source code which provides context for the suggested changes: https://github.com/carbon-design-system/carbon/blob/main/packages/react/src/components/Dropdown/Dropdown.js
• If this PR brings the type definitions up to date with a new version of the JS library, update the version number in the header.

Add or edit tests isn't checked because from what I can see from the Carbon test the optional props are still provided, and so I don't think any change to the tests is needed
