Description

How would this feature be useful?

Since 0.15 pipx got rid of the --spec argument, but now I can’t upgrade a package to a difference spec. Previously I could

pipx install virtualenv

# Some time later…
pipx upgrade virtualenv --spec "virtualenv>=30.0b2"
pipx upgrade virtualenv --spec "git+https://github.com/pypa/virtualenv.git"

Describe the solution you'd like

Either add back the --spec argument for upgrade, or allow e.g.

# Current fails with "Package cannot be a url"
pipx upgrade "git+https://github.com/pypa/virtualenv.git"

# Current fails with "FileNotFoundError"
pipx upgrade "virtualenv>=30.0b2"

Contributor guide

Research direction
Examine the pipx codebase to find where the upgrade command is implemented (likely in commands/upgrade.py or similar), and add a spec option that mirrors the spec option in the install command, then test the change.
