Choose version when installing via url

[EiyuuZack]

Hello,

When installing Xcode via --url flag the version parameter does not seem to take any effect. For example:

xcversion install 13_beta_4 --url=<url_to_xcode_13_beta_4.xip>
xcversion install "13 beta 5" --url=<url_to_xcode_13_beta_5.xip>
xcversion install 13.0 --url=<url_to_xcode_13.xip>

When calling xcversion installed I expect to see:

13 beta 4	(/Applications/Xcode-13_beta_4.app)
13 beta 5	(/Applications/Xcode-13_beta_5.app)
13.0	(/Applications/Xcode-13.0.app)

But instead I get:

13.0	(/Applications/Xcode-13_beta_4.app)
13.0	(/Applications/Xcode-13_beta_5.app)
13.0	(/Applications/Xcode-13.0.app)

This makes it harder to manage the installations.

Is this a bug or intended behaviour?
