i18n: fix typos found during l10n for git 2.34.0

Emir and Jean-Noël reported typos in some i18n messages when preparing
l10n for git 2.34.0.

* Fix unstable spelling of config variable "gpg.ssh.defaultKeyCommand"
  which was introduced in commit fd9e226 (ssh signing: retrieve a
  default key from ssh-agent, 2021-09-10).

* Add missing space between "with" and "--python" which was introduced
  in commit bd0708c (ref-filter: add %(raw) atom, 2021-07-26).

* Fix unmatched single quote in 'builtin/index-pack.c' which was
  introduced in commit 8737dab (index-pack: refactor renaming in
  final(), 2021-09-09)
