`upgrade-all` does not allow specifying `--pip-args`

[Finkregh]

Describe the bug

When I install packages from additional repos I have to e.g. set --pip-args="--extra-index-url=https://foo". Following #1441, this is not remembered for an upgrade.

When using upgrade foo --pip-args=xxx it works.

How to reproduce

• install a package from an additional repo (see above)
• upgrade-all does not support --pip-args; neither as first nor as last arg
  • pipx --pip-args="xx" upgrade-all fails
  • pipx upgrade-all --pip-args="xx" fails

Expected behavior

--pip-args supported when running upgrade-all
