Hi @heitortsergent, are these changes correct? Could you take a look? Thanks! 🙇

[inancgumus]

thanks for fixing this! Everything looks good on the Grafana docs side, but could you please undo the changes to the legacy docs under the src/data/markdown folder?

@heitortsergent, thanks for the review! I wasn't sure about that, and glad that I asked for your review :-] (thanks!). Reverted https://github.com/grafana/k6-docs/pull/1599/commits/691bbc0c3d4a1f127bdc16d3dbc16ff0616c7340.
