Better Workflow for this repo

Automated Contribution

This repo is actually using GitHub as an DB. Now, if one wants to contribute to this repo, he has to modify the README.md & data.js (which is even sorted, have to find correct place to insert new plugin).
That's quite compilcated. We can actually use GitHub Actions:

1. If one want's to submit new plugin, he submit an issue in template
2. Github Actions triggered by the issue, and creates a PR containing update to data.js and README, with a "Close #XXXX" linked back to the issue
3. Writer of this repo can then review and pass the PR
   In this way we can make the "DB" insertion more friendly

Automated Update Check

Secondly, the last update time is still manually measured. Considered that most plugins are hosted on github, we can actually make a cron gitthub action to automatically check all plugin's update time.

The updater then automatically updates README and data.js, which release repo owner from updating everything manually
