docs(ui): update Welcome page screenshot and button text

[swagatika60]

Closes #3536.

This update brings the UI documentation in line with the recent Welcome page changes introduced in kestra-io/kestra#13803.
I’ve updated the Welcome page screenshot and adjusted the button text in the documentation so it matches the new button name shown in the UI.

Hey @MilosPaunovic ,I have opened another PR as requested and have completed most of the work.
Could you please assign this issue to me? Thank you!

Where are the GH closing keywords?

Just a small note for the future, if you could use GitHub Keywords when opening PRs to connect it to the proper issue (to automate the entire process a bit more), it would be super helpful to us. You can read a bit more about it here (I've added closing keyword for this particular issue).

The text change is alright, but we don't want the image used as a working wireframe from the kestra-io/kestra#13803 to be used as a screenshot, we want the proper screenshot from the product.

Thanks for the clarification @MilosPaunovic !
And yes i'm looking for the changes.

[MilosPaunovic]

I've added closing keywords into description of the pull request now, but next time, if there is a pull requests without one, it will be closed.

Hello sir @MilosPaunovic ,
I have replaced the wireframe-style image with a real product UI screenshot .Let me know if any further changes are needed.
Thanks!

[MilosPaunovic]

Closing keywords should be added to PR description, not to the comment.

[MilosPaunovic]

Your image looks kind of blurry.

We'll take it from here, @aj-emerich will make the proper screenshot and update the PR once he's back from holiday.

Thanks for your work so far @swagatika60, it's much appreciated! 🍀

[swagatika60]

Thanks a lot for the clarification🙏.

@MilosPaunovic LGTM with the screenshot, anything else to consider?

[MilosPaunovic]

Nope, if you're okay with it, you can proceed with the merge as far as I'm concerned.
