This is necessary for the *next* commit.

In Vue 2 and Vue 3 modes, the `#storybook-root` and
`.vue-component-mounted` selectors point to the same element. In hybrid
Vue mode, the first is the parent of the second.

Since we own and append the `vue-component-mounted` class, that's all we
need to wait for, no matter the Vue version we're running.

This means running Storybook's regular Vue 2 renderer (using the Vue 2
compiler toolchain), but using a *patched* copy of `@vue/compat` at
runtime. These patches come from
gitlab-org/gitlab@aa9167c0, and are
simply renamed to match the `@gitlab/hybrid-vue` alias here so that
`patch-package` can apply them.

This only works with full builds, not development builds, as
`vue-hot-reload-api`, a dependency of `vue-loader`, reaches into Vue 2
internals that `@vue/compat` doesn't implement (for example,
`Vue.config._lifecycleHooks`).

This is fine, since this mode is only intended to catch/prevent
regressions in compatibility of Vue 3 hybrid mode *before* they reach
the GitLab monolith.

Note that Storybook needs the runtime template compiler build of Vue,
since it relies on `template` properties for its stories. This is why
the patches patch `vue.esm-bundler.js` in the same way as
`vue.runtime.esm-bundler.js` and `vue.cjs.js`

Finally, this adds a script to make it easier to keep the patches in
this project in sync with `gitlab-org/gitlab`.

Addresses gitlab-org#19700. See
