- converted publish menu and `gh-tags-list-item` components to glimmer syntax so data attributes can be passed in via `...attributes`
- added explicit `data-test-button` bound attribute to `gh-task-button` component
- moved `modal-theme-warnings` auto-bound data attribute from JS file to explicit html attribute in template
refs TryGhost/Ghost#11863
Some `a`tags with `href` attributes that are empty are used as buttons, but since the href is not linkifying anything, they appear as text nodes to assistive technologies. Give them a `"button"` role so it is guaranteed that assistive technologies will pick them up as actionable controls.

Keeps component JS backing files and template files in the same directory which avoids hunting across directories when working with components. Also lets you see all components when looking at one directory, whereas previously template-only or js-only components may not have been obvious without looking at both directories.
- ran [codemod](https://github.com/ember-codemods/ember-component-template-colocation-migrator/) for app-level components
- manually moved in-repo-addon component templates in `lib/koenig-editor`
- removed all explicit `layout` imports as JS/template associations are now made at build-time removing the need for them
- updated `.embercli` to default to new flat component structure
