[DOC/WEB]: Resolving 'Getting started' URL ambiguity in pandas.io(Issue #32307)
The Following goals are being accomplished in this PR:
- [x] Having the navigation bar's 'Getting Started' link point to `/docs/getting_started/index.html` from `/getting_started.html`
- [x] Removing the redundant markup `pandas/web/pandas/getting_started.md`.
<!--- [x] Adding above redirecting information in `pandas/doc/redirect.csv`.-->

#32307 

> Good start! To follow through on removing the duplicate page:
> 
> * [x]  Have the navigation bar point to `/docs/getting_started/index.html`
> * [ ]  Delete [the old page](https://github.com/pandas-dev/pandas/blob/master/web/pandas/getting_started.md)
> * [ ]  [Add a redirect](https://github.com/pandas-dev/pandas/blob/master/doc/redirects.csv)

@afeld I just noticed that the `Install Pandas Now ` button also leads to `getting_started.html`. In this case would it be valid to carry out the second task, i.e, "Delete [the old page](https://github.com/pandas-dev/pandas/blob/master/web/pandas/getting_started.md)", or should we redirect that link too? what do we need to do there @jorisvandenbossche @afeld  I'm probably biased, but I'm -10 here.

I don't see the duplication on those pages. For a user without knowledge of Python, Jupyter, Conda... The page you are removing is a great starting point, and they should be able to get a pandas hello world with further research. The Getting started in the docs does not accomplish that, and assumes you've got a Python working environment, and provides lots of information that is intimidating for someone just starting.

I think we're doing a very poor favor to many our users by removing this page. Thanks for the PR, but appears that this change needs more discussion on the original issue first before coming to a conclusion. Since discussion here has generally stalled, closing for now
