Should we also add these for older versions of k6? 🤔

PS: Note this is kinda related to the open question I left in the other PR for jslib docs.

[heitortsergent]

Left some suggestions, mostly removing some unnecessary lines. 🤓 I think the main content looks good!

@joanlopez I gave it a shot, but it feels more like a burden than anything else. If you don't mind, I would like for us to elaborate a more robust solution for jslibs documentation versioning in general first, and keep the PR as-is 🙇🏻

@oleiade if this applies to latest, I can port those changes over and commit directly here if you don't mind.

[oleiade]

@heitortsergent If you have the mental space for it, that would be very much appreciated 🙏🏻 🙇🏻

@oleiade I applied the changes to latest.
