## Pull Request Description
Added a button that allows quick addition of the repo to AltStore from
an iDevice. Due to the README not allowing 'altstore://' links, I had to
do it through a link shortener. The non shortened URL is:
`altstore://source?url=https://raw.githubusercontent.com/bazzadazza72/fladder-develop/refs/heads/develop/altstore.json`
## Issue Being Fixed
No issue being fixed, just added the shortcut.
