Add information about TS SDK in the getting started guide

https://agentfield.ai/guides/getting-started/build-your-first-agent

Currently there is a section titled - Python vs Go: Choose Your Path

Since Agent Field also supports a TypeScript SDK, either that should be added as well to this comparison or atleast a note - linking to internal documentation to the TS SDK.

@AbirAbbas got to take this backlog item. Been a while since tsx. Let's chat sometime this week.

Thanks for picking this up, @AbirAbbas! 🎉

Here's what to expect:

• We'll check in after 7 days if we haven't heard an update
• After 14 days, we'll send a second reminder
• After 21 days without activity, we'll unassign to let others contribute

Tips for success:

• Drop a comment when you start working on it
• Share any blockers - we're here to help!
• Link your PR with Fixes #168 in the description

Happy coding! 🚀
