Add workflow to update examples in README.md

Fixes #43

Good idea! Btw, instead of giving two examples perhaps you could add just one plus the command to list the others instead? jbang catalog list jbangdev

Edit: although what we should actually do is create a GitHub action that on each change to the catalog file runs jbang catalog2readme@jbangdev and updates the README :-)

Thank you for the neat idea! I put it on my SkedPal TODO List and it will eventually show up 😅.

Side track: I am confused with https://github.com/jbanghub/jbang-catalog and this repository. But it is how it is... Same naming across different organizations is nice. Only have troubles with GitHub forks, because I forked both - to get jbanghub/jbang-catalog#3 into the main catalog :)

Added the workflow. Works:

@quintesse May I ask for some time to look into this PR?

Looks good!

Steps to update README.md:

1. Merge this workflow in
2. Trigger it manually

After that on each update of the catalog json, there will be a new commit udpating README.md

sorry for missing this - but this seems similar to what got merged to update readme.md, right?

Title misleading. This adds a workflow updating the README. No manual updates required anymore.
