OS job doesn't respect existing tags

The os jobs overrides tags, which can lead to undesired runner selection.

For example, in:

include
  - component: "${CI_SERVER_HOST}/ci/component/bazelisk/os@1.2.0"
    inputs:
      extends:
        - .base

.base:
  extends: .job
  tags:
    - arm64
    - dind

The tags arm64 and dind aren't respected.
