chore(ui): rename "NAME PATTERN" to "NAME CONTAINS" in workflow template filters

[nakatani-yo]

Motivation

The filter label "NAME PATTERN" on the Workflow Templates page is misleading. As shown in the ListWorkflowTemplates function in server/workflowtemplate/workflow_template_server.go, the server-side name filtering uses strings.Contains for simple substring matching, not regex or glob pattern matching:

// Enables name-based searching.
// Do name pattern filtering if NamePattern request exist.
var items []v1alpha1.WorkflowTemplate
if req.NamePattern != "" {
    for _, item := range wfList.Items {
        if strings.Contains(item.Name, req.NamePattern) {
            items = append(items, item)
        }
    }
    cursorPaginationByResourceVersion(items, resourceVersion, limit, wfList)
}

The UI label should accurately reflect this actual substring-match behavior.

Modifications

Renamed the filter label from "Name Pattern" to "Name Contains" in ui/src/workflow-templates/workflow-template-filters.tsx to align with the Workflow list page (ui/src/workflows/components/workflow-filters/workflow-filters.tsx), which already uses "Name Contains" for the same type of filter, and to accurately describe the substring-match behavior.

Verification

Verified in the browser that the filter label displays as "NAME CONTAINS" and the filtering behavior remains unchanged (substring match).

Documentation

No documentation changes needed — this is a UI label correction only.
