Missing es2023 target

[garysassano]

Although Microsoft added es2023 target in TypeScript last month (see this PR), esbuild still doesn't recognize it. Attempting to use es2023 with esbuild results in the following error:

Error: Invalid target "es2023" in "--target=es2023"

Sure, I can add that. I don't think it will do anything different than es2022 because all of the additions in ES2023 are APIs instead of syntax and target only cares about syntax changes. But I agree that it's weird that esbuild doesn't have an ES2023 target yet. You should be able to use es2022 instead of es2023 in the meantime.
