This partially reverts merge request
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/131712 which
upgraded vue-apollo. The upgrade of vue-apollo was causing GraphQL
subscriptions to automatically restart which is causing increased Puma
CPU saturation as well as increased log messages. We do keep a fix of
vue-apollo that allows using props directly in vue provide by adding
a patch.

Changelog: fixed

This fixes a warning from patch-package about an old patch version.

This is a follow up to
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/132044.

* multiple minor fixes

* properly gather props/model from mixins
* mimic stub tag naming from @vue/test-utils v1
* replace function props with "[Function]"

* @vue/compat does not pass slots in $scopedSlots

Updates Rails to the latest version

This avoids a spurious warning from `patch-package` about an out of date
patch successfully applying to `@rails/ujs`.

It seems that
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/124694 correctly
added a new patch for the new version 7.0.5-1, but did not delete the
patch for the old version, 7.0.5.

Updates Rails to the latest version

This adds and uses `patch-package` to remove the `data-remote` script
executation behaviour of `@rails/ujs`.
