🌱 (chore): avoid 'fs' shadowing and rename 'isPluginExectuable' to 'isPluginExecutable' (kubernetes-sigs#4647)
fix: avoid 'fs' shadowing and rename 'isPluginExectuable' to 'isPluginExecutable' Renamed local 'fs' variables and parameters to 'filesystem' to prevent shadowing of the 'io/fs' package and improve code clarity. Also corrected the typo in the function name 'isPluginExectuable', now properly named 'isPluginExecutable'. This also updates corresponding test cases to follow the same naming convention.
