Enhancement: a dedicated config for libraries

[haoqunjiang]

Should have skipLibCheck: false in that config.

But let's wait till microsoft/TypeScript#29118 lands in TypeScript so that the configuration won't be too complex.

It has been implemented in microsoft/TypeScript#50403 and been released with TypeScript 5 😄

[haoqunjiang]

tsconfig.lib.json added in v0.5.0.
As for the skipLibCheck: false configuration, now that vuejs/core#9261 has been merged, we'll add it when 3.4 stable is out and this package drops support for 3.3.

🤔 I'm still thinking about this issue.

There are still about 2/5 Vue 3.x users are on version <= 3.3 as of today.
Should I discontinue support for Vue 3.3 now or wait till the percentage drops to somewhere like 1/5? I'm a bit torn.

[haoqunjiang]

It's officially less than 1/5 of all Vue 3 downloads now.
I think we should do it.
