feat: don't override build.target if terser is 5.16.0+ #12197

Description

terser now seems to support ES2022 syntaxes.
When this part of code was introduced, terser was lacking support for ES2019+ for a while. But now terser supports new syntax in few month, so I guess we can just drop this condition.

close #12196

Looks like the build.targetdocs need to be updated:

Updated docs after vitejs#12197: `build.target` is overridden to `'es2021'` for installed Terser versions below 5.16.0 only.
