### Dependency

- #3641

### Overview
As a developer, to turn the wins card into a reusable component, we must first be able to generate a wins-data.json file of a more specific format. This issue is part of a series that aims to migrate us to the more specific format.

### Action Items

- [ ] Read the resources/instructions below to understand your task.
- [ ] Delete the AF version of our file from our codebase.
- [ ] Check and make sure that all pages in the website still appears as before this change.

### Resources/Instructions

Currently we have two json files for wins: [_wins-data.json](https://github.com/hackforla/website/blob/gh-pages/_data/external/_wins-data.json) and [wins-data.json](https://github.com/hackforla/website/blob/gh-pages/_data/external/wins-data.json). The former will henceforth be called KVF (for key-value file) and AF (for array file). AF is generated daily from a script on google while KVF appears to be an older, dysfunc version. The format in the KVF version, however, is much friendlier to formatting in liquid syntax. Therefore, we need to incrementally port our codebase to use the KVF version of the data and remove the AF version we currently use. This will be done in multiple steps:

1. Have the apps script generate both AF and KVF version.
2. Migrate all uses of AF to KVF.
3. Have the apps script stop generating the AF version.
4. Delete the AF version from our repo since it is now unused.

For this issue, we are doing step 4.
