interim install instructions for TriliumNext

[maphew]

Trilium Next doesn't have a web-clipper release yet, but the latest one from Zadam still works fine.

1. Go to https://github.com/zadam/trilium-web-clipper/releases/tag/v1.0.1 and download the .xpi file.
2. Open the Manage Extensions page >> Click on Gear Cog >> and select "Install from file" >> select the downloaded .xpi
3. After that use 3-dots menu on the Trilium Web Clipper extension >> select Preferences >> fill out your server info etc.
