Create new page for TypeScript support #1856
Description
Related to #1853.
Starting on k6 v0.57, k6 has native TypeScript support. Currently, that information is on the JavaScript compatibility mode page since users had to use the experimental-enhanced-mode to enable that.
The compatibility mode page will probably be deleted in the near future, and TypeScript support is something that more users might be interested in if they knew it was available, so we should create a separate page to highlight it.
