ci: T8490: fix typos in comments, strings, and local identifiers

Reaches a clean typos baseline for the T8490 ruleset pilot. Categories:
- Comments/docs: recursivly, taret, passsed, characted, arhive, AtrributeError;
  "ned" -> "new" (migration comments).
- Messages/strings: writeable -> writable (x5); OCaml log "Commandis" -> "Command is".
- Local variables (all refs in-function): commited, formating, presistent;
  inpt_range -> input_range; tz_datas -> tz_data_raw (avoids the tz_data collision).
- Self-contained renames (definition + all references in-file): formated_stats,
  _get_formatted_output_conections -> ..._connections, expension_failure ->
  expansion_failure (ping + traceroute), snmpd_restart_reqired -> ..._required.

False positives are allowlisted centrally (vyos/.github, separate PR), NOT changed
here: mke2fs, Maya-calendar "Mak", RFC 4122 "IDentifier" (hostapd), and VPP's
"U-Forwrd" bridge-domain column header (op_mode/vpp.py + the VPP smoketest assert
the real upstream `vppctl` output). Verified: typos clean, py_compile of every
edited .py, zero remaining old-identifier references.
