repl: improve tab completion on computed properties

[dario-piotrowicz]

improve the tab completion capabilities around computed properties by replacing the use of brittle and error prone Regex checks with more robust AST based analysis

Followup from #58709

Note: I'm removing this comment since I think that it is inaccurate (and as a consequence misleading), since various type of lines pass through here, like for example { a: true }

I think/hope that the code structure makes it clear enough what this else if block is for (I also have half a mind to do some refactoring to also make things clearer later on 🤔)

This doesn't land cleanly on v22.x-staging, we'd need a backport PR if we want it on v22.x
