Add package name argument to `wp package update`

[baizmandesign]

The wp package update command updates all outdated packages. I'd like to be able to update one specific package like so:

wp package update vendor/package-name

I'm also tempted to suggest bringing it in line with the plugin update and theme update commands, which at minimum would...

• require one or more package name arguments (which, I acknowledge, breaks existing functionality, and is very bad)
• suggest the addition of an --all flag to re-implement the current behavior (wp package update --all)

Thoughts?

Let's start with supporting one or more packages to be updated, maintaining backward compatibility.

@swissspidy Starting with specifying one or more packages to be updated sounds good. I'll get working on it soon and submit a PR when it's ready. (Some of the Behat testing framework is still a bit foreign to me, and I may need to request your assistance with it.)

No worres :) Happy to help with the setup!

I actually had Copilot draft something in #208 if you wanna check it out.

@swissspidy Thanks! I'll take a look at it shortly. :-)
