Write some code to achieve what you need. Here I have written a simple solution for you. Try it, it should do what you want

<script type="text/x-handlebars" data-template-name="/connectors/discovery-list-controls-above/tag-h2">
<h2>
    {{#if h2_tag}}
        {{h2_tag}}
    {{/if}}
</h2>
</script>

<script type="text/discourse-plugin" version="0.8">
api.registerConnectorClass("discovery-list-controls-above", "tag-h2", {
  setupComponent(args, component) {
    if (window.location.pathname?.startsWith("/tag/"))
        component.set("h2_tag", /\/tag\/([^?]+)/.exec(decodeURI(window.location.pathname)).at(1));
  },
});
</script>
