build(deps-dev): bump esbuild from 0.14.25 to 0.14.26

[dependabot]

Bumps esbuild from 0.14.25 to 0.14.26.

Release notes

Sourced from esbuild's releases.

v0.14.26

• Fix a tree shaking regression regarding var declarations (#2080, #2085, #2098, #2099)

  Version 0.14.8 of esbuild enabled removal of duplicate function declarations when minification is enabled (see #610):

  // Original code
  function x() { return 1 }
  console.log(x())
  function x() { return 2 }
  // Output (with --minify-syntax)
  console.log(x());
  function x() {
  return 2;
  }

  This transformation is safe because function declarations are "hoisted" in JavaScript, which means they are all done first before any other code is evaluted. This means the last function declaration will overwrite all previous function declarations with the same name.

  However, this introduced an unintentional regression for var declarations in which all but the last declaration was dropped if tree-shaking was enabled. This only happens for top-level var declarations that re-declare the same variable multiple times. This regression has now been fixed:

  // Original code
  var x = 1
  console.log(x)
  var x = 2
  // Old output (with --tree-shaking=true)
  console.log(x);
  var x = 2;
  // New output (with --tree-shaking=true)
  var x = 1;
  console.log(x);
  var x = 2;

  This case now has test coverage.

• Add support for parsing "instantiation expressions" from TypeScript 4.7 (#2038)

  The upcoming version of TypeScript now lets you specify <...> type parameters on a JavaScript identifier without using a call expression:

  const ErrorMap = Map<string, Error>;  // new () => Map<string, Error>
  const errorMap = new ErrorMap();  // Map<string, Error>

  With this release, esbuild can now parse these new type annotations. This feature was contributed by @​g-plane.
