Bump esbuild from 0.20.1 to 0.21.4

[dependabot]

Bumps esbuild from 0.20.1 to 0.21.4.

Release notes

Sourced from esbuild's releases.

v0.21.4

• Update support for import assertions and import attributes in node (#3778)

  Import assertions (the assert keyword) have been removed from node starting in v22.0.0. So esbuild will now strip them and generate a warning with --target=node22 or above:

  ▲ [WARNING] The "assert" keyword is not supported in the configured target environment ("node22") [assert-to-with]
  example.mjs:1:40:
    1 │ import json from "esbuild/package.json" assert { type: "json" }
      │                                         ~~~~~~
      ╵                                         with
  
  Did you mean to use "with" instead of "assert"?
  

  Import attributes (the with keyword) have been backported to node 18 starting in v18.20.0. So esbuild will no longer strip them with --target=node18.N if N is 20 or greater.

• Fix for await transform when a label is present

  This release fixes a bug where the for await transform, which wraps the loop in a try statement, previously failed to also move the loop's label into the try statement. This bug only affects code that uses both of these features in combination. Here's an example of some affected code:

  // Original code
  async function test() {
    outer: for await (const x of [Promise.resolve([0, 1])]) {
      for (const y of x) if (y) break outer
      throw 'fail'
    }
  }
  // Old output (with --target=es6)
  function test() {
  return __async(this, null, function* () {
  outer: try {
  for (var iter = __forAwait([Promise.resolve([0, 1])]), more, temp, error; more = !(temp = yield iter.next()).done; more = false) {
  const x = temp.value;
  for (const y of x) if (y) break outer;
  throw "fail";
  }
  } catch (temp) {
  error = [temp];
  } finally {
  try {
  more && (temp = iter.return) && (yield temp.call(iter));
  } finally {
  if (error)
  throw error[0];
  }
  }
