New plugin: Furigana Logseq

I really like using logseq for studing languages because I can link common misconceptions, false friends, explaining how I translated something, etc.

There was just one thing missing, using furigana was a bit complicated because I had to write a lot of HTML, while in anki furigana was as simple as using two brackets.

The experience of developing a plugin was way easier than I thought, in part thanks to @pengx17 template.

Feel free to test it and open any issues you want on GitHub.
