Fixed the broken frontend unit tests

Added the ability to display an error for unmet prerequisites

We can use this to show more informative error messages with
links to documentation etc.

Create FailedUnmetPrerequisites status to allow custom
messaging for builds that were unable to be queued due
to failing to meet prerequisites (eg. failing to create
Kubernetes namespace for deployment).

Clarify that personal access token should be sent as password for authentication.

Don't try to set any ACL on uploaded objects

Closes #59309

See merge request gitlab-org/gitlab-ce!26781

Set ACL of uploaded objects to not-public (fog-aws) or no ACL at all
(fog-google).  Value is ignored by other supported backends (fog-aliyun,
fog-openstack, fog-rackspace)

This allows uploads to GCS with ACL support disabled.

Fix failing spec in spec/features/users/login_spec.rb

Closes #59731

See merge request gitlab-org/gitlab-ce!26787

This spec would start to fail on the first of the month because the
generated text would have a zero-padded day (e.g. 01 vs 1), whereas the
expected text check used an unpadded day via the `-d` parameter in
strftime (https://apidock.com/ruby/Date/strftime). To fix this, we
use use the `d` parameter to pad zeros.

This spec was introduced recently in
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/25731.
