Major changes:
1. The `right aligned` in `<th class="one wide right aligned">` is a
no-op because it doesn't have any content
2. The `gt-df` in `<td class="sha gt-df">` was wrong, it causes UI
misalignment, a table cell shouldn't be "flex"
3. Use `gt-py-0` for `gt-pt-0 gt-pb-0`
4. Simplify the layout for buttons, because the `text right aligned` is
widely used and good enough, it doesn't make sense to introduce the
`<div class="gt-df gt-je">`
5. Escape the `$.FileName` correctly
