Bump esbuild from 0.17.19 to 0.18.3

[dependabot[bot]]

Bumps esbuild from 0.17.19 to 0.18.3.

Release notes

Sourced from esbuild's releases.

v0.18.3

• Fix a panic due to empty static class blocks (#3161)

  This release fixes a bug where an internal invariant that was introduced in the previous release was sometimes violated, which then caused a panic. It happened when bundling code containing an empty static class block with both minification and bundling enabled.

v0.18.2

• Lower static blocks when static fields are lowered (#2800, #2950, #3025)

  This release fixes a bug where esbuild incorrectly did not lower static class blocks when static class fields needed to be lowered. For example, the following code should print 1 2 3 but previously printed 2 1 3 instead due to this bug:

  // Original code
  class Foo {
    static x = console.log(1)
    static { console.log(2) }
    static y = console.log(3)
  }
  // Old output (with --supported:class-static-field=false)
  class Foo {
  static {
  console.log(2);
  }
  }
  __publicField(Foo, "x", console.log(1));
  __publicField(Foo, "y", console.log(3));
  // New output (with --supported:class-static-field=false)
  class Foo {
  }
  __publicField(Foo, "x", console.log(1));
  console.log(2);
  __publicField(Foo, "y", console.log(3));
  

• Use static blocks to implement --keep-names on classes (#2389)

  This change fixes a bug where the name property could previously be incorrect within a class static context when using --keep-names. The problem was that the name property was being initialized after static blocks were run instead of before. This has been fixed by moving the name property initializer into a static block at the top of the class body:

  // Original code
  if (typeof Foo === 'undefined') {
    let Foo = class {
      static test = this.name
    }
    console.log(Foo.test)
  }
  // Old output (with --keep-names)
  if (typeof Foo === "undefined") {
