This brings back many of the changes in
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/27276. This was
reverted due to some failures in the QA tests with nil parameters.

Grape v1.3.3 brings in Ruby 2.7 support and a number of fixes:
https://github.com/ruby-grape/grape/blob/master/CHANGELOG.md

1. Move all inherited `Grape::API` -> `Grape::API::Instance`
2. Remove use of Virtus since this has been removed from Grape.
3. Extract `Rack::Response` from API error
4. Grape v1.2.3 pulled in a fix used in `SafeFile`:
https://github.com/ruby-grape/grape/pull/1844, so we no longer need
to maintain our custom type.
5. Adapt `WorkhorseFile` with the latest changes to make custom types
work with Grape and dry-types.
6. Ensure `Array[String]` is coerced properly.

The change from Virtus to dry-types now requires all strings to be
coerced to arrays. Before this was done within Virtus.

7. Coerce `Array[Integer]` types to arrays of integers

8. Use a new helper, `coerce_nil_params_to_array!`, that coerces nil
Array inputs to empty arrays to preserve previous behavior.

If you have a parameter of type `Array[String]`, for example, Grape used
to coerce a provided `nil` value to `[]`. Grape no longer does this for
us, so we need a helper method that will automatically do this if the
parameter is present.

This merge request also introduces two Rubocop rules for Grape v1.3:

1. `Grape::API::Instance` instead of `Grape::API` is required, unless we
solve https://gitlab.com/gitlab-org/gitlab/-/issues/215230.

2. Grape parameters defined with `Array` types (e.g. `Array[String]`,
`Array[Integer]`) must have a `coerce_with` block or they will fail to
parse properly. See
https://github.com/ruby-grape/grape/blob/master/UPGRADING.md for more
details.

Resolve "Display non-markdown content in the WYSIWYG mode of the SSE::Identifiers"

Closes #221082

Resolve "Add no graph empty state for DAG"

See merge request gitlab-org/gitlab!35053

We add a new empty state to the graph
so that we can redirect users to the
job dependencies documentation and
educate them on this architecture.
This should only appears when there
is not enough data to render the graph
and there are no errors while parsing the
data.
