build: correct d.ts output dir in development

[fi3ework]

Description

In dev mode for vite, d.ts is generated to dist/dist/node which is not correct.

While package.json is write as

vite/packages/vite/package.json

Lines 20 to 31 in 2aad552

	"types": "./dist/node/index.d.ts",
	"exports": {
	".": {
	"types": "./dist/node/index.d.ts",
	"import": "./dist/node/index.js",
	"require": "./index.cjs"
	},
	"./client": {
	"types": "./client.d.ts"
	},
	"./dist/client/*": "./dist/client/*",
	"./package.json": "./package.json"

So no d.ts could be found in dev mode.

Change the abs path to a relative path to correct the output behavior. I haven't quite figured out the logic here https://github.com/rollup/plugins/blob/bc5cf91a042b88e14a1da9ba25f501d92591ca8a/packages/typescript/src/index.ts#L152-L182. But seems like it's more conventional to use a relative path as output.dir. So I changed it to relative path and everything goes well now. 😅

Oh wow the entire time I just thought they weren't types in dev 🥲 Thank you so much for this, I tested locally and it works for me too.
