Update 5 BYOH test names with "Byoh-" prefix

Description

Update 5 BYOH test names in test/extended/winc/winc.go to include "Byoh-" prefix for proper test filtering.

Tests to Update

All tests use setBYOH() function:

1. Line ~387: OCP-42496-Author:xxia-High-ConnectedOnly-Configure a Windows instance with DNS
2. Line ~420: OCP-42484-Author:xxia-High-ConnectedOnly-Configure a Windows instance with IP
3. Line ~468: OCP-42516-Author:xxia-High-ConnectedOnly-Configure a Windows instance with IP and DNS
4. Line ~1554: OCP-44099-Author:xxia-Critical-ConnectedOnly-Secure Windows workers username annotation
5. Line ~2967: OCP-82694-Author:xxia-Critical-ConnectedOnly-Verify containerd path removal

Example Change

// Before
It("OCP-42496-Author:xxia-High-ConnectedOnly-Configure a Windows instance with DNS", func() {
    setBYOH()
    // test implementation
})

// After
It("Byoh-OCP-42496-Author:xxia-High-ConnectedOnly-Configure a Windows instance with DNS", func() {
    setBYOH()
    // test implementation
})

Implementation Steps

1. Search for setBYOH() function calls in test/extended/winc/winc.go
2. For each test that uses setBYOH(), add "Byoh-" prefix to the test name
3. Ensure the prefix is added BEFORE the OCP number
4. Verify all 5 tests are updated

Acceptance Criteria

• All 5 BYOH tests have "Byoh-" prefix
• Test names follow format: Byoh-OCP-XXXXX-...
• No duplicate test names introduced
• All tests continue to call setBYOH()
• make test passes
