[NO JIRA]: Correct React semver range

[olliecurtis]

This PR corrects the semver range for the react dependencies. As it turns out ^x.x.x - x.x.x is not correct syntax for the range and we need to drop the ^ when using a - range

More detail here: https://semver.npmjs.com/#syntax-examples

Without it it causes the following errors on install:

While resolving: <dependency-name-here>@0.0.0
   Found: react@18.3.1
   node_modules/react
     dev react@"18.3.1" from the root project
   Could not resolve dependency:
     peer react@"^17.0.2 - 18.3.1" from @skyscanner/backpack-web@35.0.0
     node_modules/@skyscanner/backpack-web
        dev @skyscanner/backpack-web@"^35.0.0" from the root project

Remember to include the following changes:

• Ensure the PR title includes the name of the component you are changing so it's clear in the release notes for consumers of the changes in the version e.g [KOA-123][BpkButton] Updating the colour
• README.md (If you have created a new component)
• Component README.md
• Tests
• Accessibility tests
  • The following checks were performed:
    • Ability to navigate using a keyboard only
    • Zoom functionality (Deque University explanation):
      • The page SHOULD be functional AND readable when only the text is magnified to 200% of its initial size
      • Pages must reflow as zoom increases up to 400% so that content continues to be presented in only one column i.e. Content MUST NOT require scrolling in two directions (both vertically and horizontally)
    • Ability to navigate using a screen reader only
• Storybook examples created/updated
• For breaking changes or deprecating components/properties, migration guides added to the description of the PR. If the guide has large changes, consider creating a new Markdown page inside the component's docs folder and link it here
