code transformed string still retain paths which configred by tsconfig.json

Hi,

I use `rollup-plugin-esbuild` to build file, and i found it's use transform API internal. After build files, i found they are still retain path which configured in `tsconfig.json` in rootDir.

At first, i think it's maybe the bug from rollup-plugin, but after i used `cat path/to/file | esbuild --loader=tsx` try to review what esbuild output original, I found there's nothing changed:

```shell
~/workspace/neutron refactor/packages*
❯ cat src/components/easy-form/index.tsx | esbuild --loader=tsx
import React from "react";
import get from "lodash/get";
import isNil from "lodash/isNil";
import merge from "lodash/merge";
import isObjectLike from "lodash/isObjectLike";
import {Button, Form} from "zent";
import {EasyFormPreview} from "./components/preview";
import {useFormConfigs} from "./hooks/use-form-configs";
import useUpdateTimes from "@hooks/use-update-times";
import {group} from "./utils/get-group-config";
import {list} from "./utils/get-list-config";
import {invariant} from "./utils/invariant";
import {RenderField} from "./components/render-filed";
import {useFormWatches} from "./hooks/use-form-watches";
import {propWalker} from "./utils/props-walker";
const {useForm, ValidateOption} = Form;
```

And that my `tsconfig.json`:

```json
{
"compilerOptions": {
"baseUrl": ".",
"paths": {
"@components/*": ["./src/components/*"],
"@utils/*": ["./src/utils/*"],
"@hooks/*": ["./src/hooks/*"]
},
"removeComments": false,
"strictNullChecks": true,
"moduleResolution": "Node",
"esModuleInterop": true,
"experimentalDecorators": true,
"jsx": "react",
"noUnusedParameters": true,
"noUnusedLocals": true,
"noImplicitAny": true,
"target": "es6",
"lib": ["dom", "es2018"],
"skipLibCheck": true
},
"include": ["./src/**/*"],
"exclude": ["node_modules", "lib", "es", "__test__"]
}

```

Start by reproducing the shown `esbuild --loader=tsx` command with the supplied `tsconfig.json`, focusing on the `baseUrl` and `paths` entries. Then trace the transform API entry point and its handling of TSX imports; done means the expected treatment of configured path aliases is documented by a regression test.
