fix(esbuild): import esbuild correctly

[dfrkp]

The previous way of importing esbuild would lead the error:

node_modules/@linaria/esbuild/lib/index.js:74:29: error: [plugin: linaria] Cannot read property 'transformSync' of undefined
74 } = _esbuild.default.transformSync(rawCode, { ...esbuildOptions,

Motivation

When using linaria with esbuild as described here: https://github.com/callstack/linaria/blob/master/docs/BUNDLERS_INTEGRATION.md#esbuild one would get a failing build due to the import not working as expected. Error message:

    74 │         } = _esbuild.default.transformSync(rawCode, { ...esbuildOptions,
       ╵                              ^

    at Socket.Readable.push (node:internal/streams/readable:226:10)
    at Pipe.onStreamRead (node:internal/stream_base_commons:190:23)```

## Summary

esbuild does export `transformSync` just fine and hence it can be imported like the other interfaces.

## Test plan

To test this, you'll need a simple esbuild project. And add the build config (to build.js):

const { build } = require("esbuild");
const linaria = require("@linaria/esbuild");

const prod = process.env.NODE_ENV === "production";

build({
entryPoints: ["./src/index.tsx"],
outdir: "dist",
minify: true,
bundle: true,
plugins: [
linaria.default({
sourceMap: prod,
}),
],
}).catch(() => process.exit(1));

Now the build should work and not fail with the previously mentioned issue.
