Add peerDependency warning if using < typescript 5

[EliBates]

I discovered this issue using nextjs when when using typescript < 5.
#352

This adds a peerDependency of typescript 5 so that anyone installing valibot will be warned if they don't have the appropriate version of TypeScript installed in their project.

The idea is great, but there is one problem. If someone is not using TypeScript, this change will erroneously display a warning when installing Valibot.

@fabian-hiller Good point. I think we can add:

  "peerDependenciesMeta": {
    "typescript": {
      "optional": true
    }
  }

This should make it warn only users who are using typescript. I think this will be helpful because I still see a lot of projects on <5 typescript.

Thank you! I will review this PR in the next few days.

One thing to note about the TypeScript project is that it does not follow SemVer, and breaking changes can be introduced in minor versions.

You might want to be more explicit about versions that are compatible with the tilde syntax:

Suggested change

	"peerDependencies": {
	"typescript": ">=5"
	},
	"peerDependencies": {
	"typescript": "~5.0||~5.1||~5.2||~5.3"
	},

Or even just a more specific range:

Suggested change

	"peerDependencies": {
	"typescript": ">=5"
	},
	"peerDependencies": {
	"typescript": "=5"
	},

Sorry for not picking up this PR yet. Other things had a higher priority. I expect to review it this month.
