Update YAML file Test_TC_OPCREDS_3_7

[juandediosg]

This PR updates the TC_OPCREDS_3_7 YAML file by removing steps to align the test procedure with the Fixes: #423

Updates:

• The YAML test script was updated to reflect these changes.
• The TC_OPCREDS_3_7 test procedure in the test plan has been updated in PR #4820.

Testing for Multiple Fabrics:

This test validates the TC_OPCREDS_3_7 procedure when two fabrics, gamma and the default alpha, are present on the Device Under Test (DUT). The process includes commissioning the DUT with gamma using the --commissioner-name gamma flag, opening a commissioning window, re-commissioning with alpha, and confirming the test passes successfully with both fabrics in use.

Example of Test Steps (Passed):

1. In the first console, Run the all-clusters app:

   rm /tmp/chip_*                                        
   ./out/darwin-arm64-all-clusters/chip-all-clusters-app

2. In the second console, Perform the first commissioning:

   ./out/darwin-arm64-chip-tool/chip-tool pairing code 0x12344321 749701123365521327694 --commissioner-name gamma
   Note: As example I use the manual pairing code 749701123365521327694 instead of the QR code payload ID MT:Y.K9042C00KA0648G00.
   

3. Opened the commissioning window and searched for "Manual pairing code" in the output:

   ./out/darwin-arm64-chip-tool/chip-tool pairing open-commissioning-window 0x12344321 1 300 1000 2365 --commissioner-name gamma

4. Re-commissioned with a second commissioner (alpha):

   ./out/darwin-arm64-chip-tool/chip-tool pairing code 0x12344321 23064351703 --commissioner-name alpha

5. In the third console, Run the test:

   ./scripts/tests/chipyaml/chiptool.py tests Test_TC_OPCREDS_3_7 --server_path ./out/darwin-arm64-chip-tool/chip-tool.

6. As result:

   ***** Test Complete: Test_TC_OPCREDS_3_7
   ✓ Test finished in 1344ms with 35 success, 0 errors and 0 warnings
   ✓ Parsing finished in 8ms with 1 success and 0 errors.
   Run finished in 2548ms with 16 steps runned and 0 steps skipped.
   

Changes made:

• Removed the factory reset from the YAML file.
• Adjusted the test procedure to align with the updated format from the linked test plan PR.
