Unexecutable due to Case Conversion of Suffixes

[ShiYioo]

• VS Code Version: 1.102.3
• OS Version: Windows 11 24H2
• Code Runner Version: 0.12.2

Describe the bug

Code language not supported or defined.

To Reproduce

After I created a file named test.KT and then converted it to test.kt, after running it, the Code Runner plugin shows Code language not supported or defined.

Although converting test.kt to test1.kt to test.kt solves the problem, it's probably a limitation of my knowledge to consider him as a bug
