https://gitlab.com/gitlab-org/gitlab-services/design.gitlab.com/-/issues/2249 removed the usage from in `BFormCheckbox` `GlFormCheckbox`. The problem is that `BFormCheckboxGroup` does use `BFormCheckbox` if I'm not mistaken via [`mixins/form-radio-check-group.js`](https://gitlab.com/gitlab-org/gitlab-services/design.gitlab.com/-/blob/gl-form-checkbox-migration/packages/gitlab-ui/src/vendor/bootstrap-vue/src/mixins/form-radio-check-group.js#L9), so I think we need to migrate GlFormCheckboxGroup first. Afterwards, we can remove the traces: - Remove packages/gitlab-ui/src/vendor/bootstrap-vue/src/components/form-checkbox/form-checkbox.js - Remove packages/gitlab-ui/src/vendor/bootstrap-vue/src/components/form-checkbox/form-checkbox.spec.js - Remove entry from packages/gitlab-ui/src/vendor/bootstrap-vue/src/components/form-checkbox/index.js - Remove entry from packages/gitlab-ui/src/vendor/bootstrap-vue/src/components/form-checkbox/package.json - Remove BCheckbox specific docs from packages/gitlab-ui/src/vendor/bootstrap-vue/src/components/form-checkbox/README.md - Remove imported consts, functions, mixins, etc. which might have been used in the now removed code
