misc: Use 'and' joined summary for install/uninstall

[kamilogorek]

It's a cosmetic change, that modifies how installed/uninstalled crates are listed. When precisely two are installed, it just reads oddly right now IMO.

Note that https://crates.io/crates/and crate is reserved, so there will never be something and and.

A: Summary Successfully installed tauri-cli, trunk!
B: Summary Successfully installed tauri-cli and trunk!

A: Summary Successfully installed tauri, tauri-cli, trunk!

Looking at the test output, I feel like using and makes it harder to quickly scan. Using an oxford comma would help but that doesn't help with the foo and bar (2 item) case.

Gotcha, makes perfect sense, as it's subjective. I'm fine closing the PR, so no worries :)
