fix(devti): correct language detection in code blocks #101

The commit corrects an issue where the code block language was not being detected correctly for `csharp` and `fsharp`. The language names have been updated to their standard forms, and the file type is now correctly set to PlainTextFileType if the original file type is UnknownFileType.
