chore(React19): Enable React 19

[rebeccaalpert]

1. Dropped React imports and added peer dep for 19
2. Ran npx codemod react/update-react-imports --target ./packages/module
3. Fixed TS build errors
4. Ran npx prettier --write packages/module
5. Manually fixed example imports since the codemod didn't get them

Testing:

• Tried pulling in @patternfly/documentation-framework@"6.9.11" and updating PF deps to the pre-release versions in that version, but then other things have problems because they don't have access to the pre-releases:

• Talked to Nicole and she suggested that I can test this in the demo we used for usability testing - I should be able to pull in React 19 there and avoid the circular dependencies in theory, but I would need this to merge first.

I'm a little confused about the MouseEvent params (previously we specified React.MouseEvent and native MouseEvent, and with the codemods now it only uses react's import of MouseEvent, losing the native one). Not sure if we still need to cover both explicitly or not.

Another general note is that I'm wondering if we want to keep the React.X notation on prop definitions for our docs. I don't think the build complains about having it there (still leaving out the overall react import), and I've noticed we still have it in the react-core's props. It may not be a big deal to leave this as is with the types imported, as it's usually pretty evident it's a react type for things like ReactNode.

Addressed comments and rebased!

Do we need to remove these from the devDeps?

[rebeccaalpert]

Katie asked me to put them back in in the other package.json...do we need both?
