Extend GetCollectionItems use case: add show_relevance

In the Collections page, when a term is entered in the search bar, the collection items should show snippets with the search term highlighted. To do this, we need to update GetCollectionItems to call the Dataverse search api with show_relevance=true.

For example, when searching for 'King' in Dataverse, the snippets of metadata that contain king are shown, and for the description field, 'King' is highlighted.
In the JSF, we are only highlighting the search term in the description, but using the API we could also highlight the term in other metadata.

The API for this example:
https://dataverse.harvard.edu/api/v1/search?show_relevance=true&q=king&show_facets=true&sort=score&order=desc&subtree=harvard&per_page=10&type=dataverse&type=dataset&type=file

In the response, the matches array contains the snippets to be displayed:

In response to the data-based measures of model dependence proposed in King and Zeng (2006), Sambanis and Michaelides (2008) propose alternative measures that rely upon assumptions untestable in observational data. If these assumptions are correct, then their measures are appropriate and ours, based solely on the empirical data, may be too conser vative. If instead and as is usually the case, the researcher is not certain of the precise functional form of the data generating process, the distribution from whic h the data are drawn, and the applicability of these modeling assumptions to new counterfactuals, then the data-based measures proposed in King and Zeng (2006) are much preferred. After all, the point of model dependence checks is to verify empirically, rather than to stipulate by assumption, the effects of modeling assumptions on counterfactual inferences.",

从 GetCollectionItems 用例开始，跟踪 Collections 页面如何构建其 Dataverse 搜索请求并渲染结果。验证输入搜索词时请求包含 show_relevance=true，然后确认响应的 matches 数组中的摘要会在元数据字段中以高亮术语显示。
