feat: vite connected logs changed to console.debug

[WORMSS]

Description

Changed log to debug to reduce spamming console

Changing this to debug from log means people can choose to show/not show this information with using Verbose on/off in devtools.
Otherwise it becomes super spammy while developing and adds nothing to the average vue developer experience

It isn't clear to me what is the best DX here. I know that @Akryum ended up hacking the Vite log messages to remove the same one in Histoire for example, so you aren't the only one that would appreciate moving them to Verbose. I'll add this PR to be discussed in a team meeting. If we do it, we should do it in Vite v3 so users aren't surprised by the messages no longer being there.

okay, I am sure its useful if you are developing Vite.. Just adds nothing if you are writing a Vue app
