feat(global-header): support multiple support links

[oskarjiang]

Hey, I just made a Pull Request!

The example for customizing the support button doesn't work. From what I can find no such functionality exists in the <SupportButton/> component currently. Here's a suggestion for how it could be implemented.

Hi @oskarjiang. Thanks a lot for your contribution, we will take a look if this still matches our needs.

Can you add a screenshots of different use cases? Otherwise maybe @Eswaraiahsapram can create some with different use cases.

When this doesn't break the current configuration we could also take this as a patch.

Thanks @oskarjiang , for your contribution. I think this should be a patch release rather than a minor one.

My intention was to simply provide a fix for the use-case in your current example. So I think that one still suffices 😊

Also I believe that this change is backwards compatible as is.
