core[patch]: Support .yml extension for YAML (#16783)

- **Description:**

[AS-IS] When dealing with a yaml file, the extension must be .yaml.  

[TO-BE] In the absence of extension length constraints in the OS, the
extension of the YAML file is yaml, but control over the yml extension
must still be made.

It's as if it's an error because it's a .jpg extension in jpeg support.

  - **Issue:** - 

  - **Dependencies:**
no dependencies required for this change,
