feat: improve linux distribution information get logic (#11171)

* feat: Add PrettyDistro field to dashboard information and update related services and frontend components

* fix: Trim whitespace and parentheses from detected Linux distribution name in GetDistro method

* fix: Correctly trim parentheses from detected Linux distribution name in GetDistro method

* refactor: Simplify Linux distribution detection by removing unnecessary checks and consolidating logic
