What does this MR do and why?

Added the web_path field to ciCatalogResource in GraphQL.

Partially resolves #407382 (closed)

How to set up and validate locally

1. In the Rails console, run Feature.enable(:ci_private_catalog_beta) and Feature.enable(:ci_namespace_catalog_experimental).
2. Create a Catalog Resource with an existing or new Project:

::Ci::Catalog::Resource.create(project: Project.find(<project_id>))

3. Go to http://gdk.test:3000/-/graphql-explorer and run the following query (adjust the projectPath as necessary):

query getCiCatalogResources {
  ciCatalogResources(projectPath: "group-a/project-catalog-resource-1") {
    nodes {
      id
      name
      webPath
    }
  }
}

4. Observe that the output shows the correct Catalog Resource data.
