Improve the Quick Start page

[flyrain]

Describe the solution you'd like

After #859, It makes more sense to deprecate the existing Quick Start page, by replacing it with the docs in directory ./getting-started.

Question: the Quick Start page is published under https://polaris.apache.org/in-dev/unreleased/quickstart/ – but the docs in directory getting-started aren't. How are users browsing https://polaris.apache.org going to find the getting-started examples if we delete the Quick Start page?

I think we could use symlink like what we did for chat-bylaws.md under the directory content.

Hi @flyrain , I was doing poc for using polaris catalog for creating iceberg table in azure data lake service, as I was doing that, i didn't find the enough documentation related to adls, it was mostly for s3, so it took me lot of time, in order to use the polaris catalog, should I create a documentation, so others can refer that?

Hi @raushanprabhakar1, definitely! Feel free to file an issue or PR for that! This is our current doc site, https://polaris.apache.org/in-dev/unreleased/. I'm OK with put this in one of existing pages, or creating a new page for storage related things.
