Frontend: Implement deprecation notification for `types` and `type` keyword

This is an implementation issue to track the deprecation of types and type keyword

types and type

• Deprecated in v9.0: gitlab-foss!9766 (merged)

We want to implement the deprecation process so we could remove types in %15.0

Proposal

Implement deprecation notice warning

This is a frontend issue

• The warning alert should NOT be permanently dismissable
• Link to point the user to https://docs.gitlab.com/ee/ci/yaml/#deprecated-keywords
• No feature flag is required

Further improvements

Phase 3 - Optional send email notification, depends on the number of users that are using types

Phase 4 - remove types - https://gitlab.com/gitlab-org/gitlab/-/issues/346823 - - Schedule for 15.0

Note - Phase 3 & 4 are out of scope for this issue``
