fix: Use frappe.as_unicode to decode output of redis module list (backport #31282) (#31283)

fix: Use `frappe.as_unicode` to decode output of redis module list (#31282)

- As of redis 7, a list is added to the result of fetching the module list
- This list cannot be "decoded",so use `frappe.as_unicode` that handles bytes as well as other types

(cherry picked from commit 2832731601)
