Broken link to Getting Started documentation redirects to unrelated website

[barne856]

Describe the bug
In the Contributing guidelines, the "Getting Started page" link (https://xarray-spatial.org/getting_started/index.html) is broken and currently redirects to an online gambling website. This presents both a documentation issue and a potential security concern for users.

Expected behavior
The Getting Started link should direct users to the proper Xarray-Spatial documentation page with installation and development environment setup instructions.

Additional context

• Location of the issue: CONTRIBUTING.md documentation file
• The broken link appears in the "Getting Started" section
• Current text:

Information about installation and setting up a development environment can be found at the [Getting Started page] https://xarray-spatial.org/getting_started/index.html.

This should be updated with the correct documentation URL once available to ensure users can properly access the getting started information.
