[teraslice-chart] Fix docs and index.yaml issue with teraslice-chart

[sotojn]

We recently added a pipeline that publishes the teraslice helm chart and create some docs located here.

There are several missed issues having to do with the new docs and some cleanup that still needs to be done in some areas.

• Add an icon to the https://terascope.github.io/teraslice/charts/ docs
• Fix the url at the bottom that leads to the oci url which is invalid in browsers
• Delete the teraslice entry in the index.yaml.
  • We would need to do this in its own PR because workflows won't trigger if this file is merged to master.
• Add the KindConfig.yaml copy and paste to the docs
• Add a link in the top level docs to helm chart docs
• Create a better "Quick Start" guide that has creative examples on how teraslice can be used
  • Perhaps bundling a side cart container with the chart that can generate data and create jobs on startup. Also autoload necessary assets

Here's where AWS lists the public datasets: https://registry.opendata.aws/

Searching it for something with csv in the description shows us the old reliable NOAA datasets:

https://registry.opendata.aws/noaa-ghcn/

Check some stuff out:

# list the files
aws s3 ls --human-readable --no-sign-request s3://noaa-ghcn-pds/csv/by_year/
...
2025-01-28 05:47:54    1.2 GiB 2024.csv
2025-01-28 05:46:23   66.4 MiB 2025.csv

# copy this years file locally
aws s3 cp --no-sign-request s3://noaa-ghcn-pds/csv/by_year/2024.csv .
download: s3://noaa-ghcn-pds/csv/by_year/2024.csv to ./2024.csv

# whats in the file
tail 2024.csv

Oh yeah, this data sucks, it needs to be pivoted.
