Add tags list for repos whose release setting is disabled (#23465) (#24369)

Backport #23465

If a repo's release setting is enabled, the logic has't changed.
Clicking the "Tags" button will jump to `/{user}/{repo}/tags` and
`templates/repo/release/list.tmpl` template will be used.

If the release setting is disabled, clicking the "Tags" button will
still jump to `/{user}/{repo}/tags` but a new template
`templates/repo/tag/list.tmpl` will be used.

Since both templates above need to render the tags list, I moved the
tags list to a shared template located in
`templates/repo/tag/table.tmpl`.
