Undocumented behaviour for non-github setup of `publish.vcs` directive

[Gedochao]

Version(s)
1.5.4

Describe the bug
Docs don't seem to specify how the //> using publish.vcs directive should be set up for non-GitHub repositories.
https://scala-cli.virtuslab.org/docs/commands/publishing/publish#other-settings
What's there (the url|connection|developer-connection format) seems quite vague.
We need examples, better errors, or some different behaviour.

To Reproduce

//> using publish.vcs https://git.qwertyuiop.de/crater2150/copret.git

yields

[error] Malformed vcs "https://git.qwertyuiop.de/crater2150/copret.git", expected url|connection|developer-connection
[error] //> using publish.vcs https://git.qwertyuiop.de/crater2150/copret.git

Expected behaviour
I'd expect the reproduction to either pass, or for documentation to provide examples how to handle non-github repositories.

Extra context

• the error seems to originate at https://github.com/VirtusLab/scala-cli/blob/main/modules/options/src/main/scala/scala/build/options/publish/Vcs.scala#L35-L48
• it seems for non-GitHub repositories, the parser expects all 3 components of the url|connection|developer-connection format
• originally reported on Discord: https://discord.com/channels/632150470000902164/901153021638082660/1326980016545861745
