feat(react): Add a new optional prop called 'prefix' to all React components for scoping web components

Here is the diff for the generated React component after these changes (PharosButton as an example):

To use this as a consumer it would look something like the following:

  <PharosLink
    prefix="mfe-heads-up-display"
    href="https://google.com"
  >
    Hello Google!
  </PharosLink>

Other thoughts:

• This should be backward compatible as I am leaving the PharosContext in there
• All of this will go away once we upgrade to React 19 where there is native support for web components.

Closing as we found a workaround. This issue will go away with React 19 where web components are supported out of the box
