refactor(fixer.go, main.go): replace regex with glob pattern for file…

- Change variable naming and logic in `fixer.go` to use `filepath.Glob` for matching files, enhancing flexibility and usability.
- Update flag description in `main.go` to reflect the change from regex to glob pattern, improving clarity for end-users.
