Bumps esbuild from 0.14.47 to 0.15.12.

Release notes

v0.15.12
Fix minifier correctness bug with single-use substitutions (#2619)

When minification is enabled, esbuild will attempt to eliminate variables that are only used once in certain cases. For example, esbuild minifies this code:
function getEmailForUser(name) {
  let users = db.table('users');
  let user = users.find({ name });
  let email = user?.get('email');
  return email;
}
into this code:
function getEmailForUser(e){return db.table("users").find({name:e})?.get("email")}
However, this transformation had a bug where esbuild did not correctly consider the "read" part of binary read-modify-write assignment operators. For example, it's incorrect to minify the following code into bar += fn() because the call to fn() might modify bar:
const foo = fn();
bar += foo;
In addition to fixing this correctness bug, this release also improves esbuild's output in the case where all values being skipped over are primitives:
function toneMapLuminance(r, g, b) {
  let hdr = luminance(r, g, b)
  let decay = 1 / (1 + hdr)
  return 1 - decay
}
Previous releases of esbuild didn't substitute these single-use variables here, but esbuild will now minify this to the following code starting with this release:
function toneMapLuminance(e,n,a){return 1-1/(1+luminance(e,n,a))}
v0.15.11
Fix various edge cases regarding template tags and this (#2610)

This release fixes some bugs where the value of this wasn't correctly preserved when evaluating template tags in a few edge cases. These edge cases are listed below:
async function test() {
