feat(cli): global upgrade supports matchspec

[chawyehsu]

A small logic tweak making global upgrade <package> support matchspec input.

before:

$ pixi g upgrade python==3.10
  × Package is not globally installed

after:

$ .\target\release\pixi.exe g upgrade python==3.11
  Updated python v3.10.0 -> v3.11.0

This is useful when they don't want to upgrade a package to the latest version but a slightly newer one.

This now doesn't allow to downgrade, what do you think of skipping the version check if the version is specified in the package argument?

example:

pixi on  feature/global-upgrade-matchspec is 📦 v0.16.1 via 🦀 v1.75.0 took 49s 
➜ pixi g upgrade uv==0.1.17
  Updated uv v0.1.16 -> v0.1.17                                                                 

pixi on  feature/global-upgrade-matchspec is 📦 v0.16.1 via 🦀 v1.75.0 took 9s 
➜ pixi g upgrade uv==0.1.16
Package uv is already up-to-date

Would be cool if that was also possible.

Yeah that will be more semantic for matchspec support.

Works like a charm! Thanks @chawyehsu
