Migrate enable Gitpod confirmation modal to `GlModal`

What does this MR do and why?

Related to #344567 (closed)

When viewing a repository tree, file blob, or MR there is an Gitpod button. If the user does not have Gitpod integration enabled yet it will display a modal asking if the user wants to enable the Gitpod integration. Currently this is a Bootstrap modal. This MR migrates that modal to GitLab UI GlModal.

@justin_ho can you review this when you have time? If everything looks good can you pass it off to @ekigbo (assuming he doesn't have a busy status).
