Mention `devTarget` option in caveats list

It's been two years since that was first written, do you think it may be time to update the default to es2022 already? (If es2020 was good in 2022, maybe es2022 is good in 2024?) Having hidden properties visible in the inspector heavily improves the debugging experience, and it took me a couple days to figure out what was transpiling them out, because I couldn't find anything in the Vite or ESBuild documentation. It only occurred to me today to check this plugin, which solved my issue & immediately resulted in this PR.

I need to review what's the current behaviour in core and align with it. There are already multiple issues in core that shows that this is not very clear for now
