DOC: Add link to the "try pandas online" in the regular documentation

[Dr-Irv]

Pandas version checks

• I have checked that the issue still exists on the latest versions of the docs on main here

Location of the documentation

https://pandas.pydata.org/docs/getting_started/index.html#getting-started

Documentation problem

In #60758, @agriyakhetarpal created a page (https://pandas.pydata.org/try.html) allowing users to try pandas online.

Suggested fix for documentation

A link to that page should appear in the docs on the Getting Started page.

Thanks, @Dr-Irv. I did add a link to the Getting Started page for the pandas website (see https://arc.net/l/quote/jdacyseq), but not for the corresponding Getting Started page in the documentation. I'm actually working on a branch that aims to build one JupyterLite deployment and consolidate it for both the documentation and the website, and I can take care of this in the same PR when it is ready. Please feel free to assign me to this.
