Add translation progress script and GitHub Action

[Nicooow]

Hi! This isn’t a functional change to QLC+, so I didn’t use the PR template this time.

I chatted with the maintainer of the QLC+ Instagram account, and he thought this was a great idea—so here’s a simple script to calculate the translation progress percentage for each language and module. It’s basic but does the job.
I’ve also added a GitHub Action that will run whenever a .ts file is modified in a PR, giving a quick update on the translation status. It might be nice to share this info more widely, though:

• Option 1: Update the Wiki page (How to translate QLC+ in your language) after each merge into master (I don’t have edit access, unfortunately).
• Option 2: Add a .md file in the repo root to guide contributors and show the progress.

I placed the script into a new scripts folder. It might be a good idea to move all .sh files there to keep the root directory cleaner.

Why not integrating this into the existing translate.sh tool?
E.g.
./translate.sh stats

You're right. I didn’t want to overload the current script. I’ve made the changes, you can check the result here

[mcallegari]

I don't like this part. It's not dynamic. If we add new ts files I need to remember about this.
The script already finds all the ts files depending on the build.
Can labels be like the folder name? like "fixtureeditor", "plugins/midi" and so on?

[Nicooow]

Yes, we can, but the result in the table will be very ugly. Maybe we can mix the two? We search for all .ts files, and if we know the path (TS_FILES), we get the friendly name, otherwise, we just put the path
