Move more helm command tests to shared examples

Closes #39460

See merge request gitlab-org/gitlab!21863

A large amount of the helm command behavior is shared behavior inherited
from BaseCommand, yet much of the test code was duplicated. This
extracts the common test code into shared examples.

Use `Array[Integer]` and coerce these to an integer arrays.

Note that if `Array` were used with this lambda, things worked work with
Grape v1.3. However, `Array[String]` did not. Standardize everything on
using `Validations::Types::CommaSeparatedToIntegerArray.coerce` with
`Array[Integer]`

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.

This brings in Ruby 2.7 suport 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

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