package/ed: bump to version 1.22.6

Changes in 1.22.6 (released 2026-08-20):
- Some changes have been made to the code to pacify gcc's static
  analyzer.
- 'regex(7)' has been added to the --help output and to section
  'SEE ALSO' in the man page.
- It has been documented in the manual that the cut buffer is deleted
  when a new file is read with 'e' or 'E'.
- It has been documented in the manual that using a regular expression
  inside the command-list of a global command may cause the "last
  regular expression processed" to differ between the first and
  subsequent executions of the command-list.
