In desktop the action "Export References" (accessible via icon in the references sidebar) uses a Tauri dialog to ask for the export file name and location (defaults to /exports/references.bib inside the project).

For the web, we need to choose the desired behaviour taking into consideration what was choose for #455.

My considerations:

1. We should also add this action to the menu (desktop) and command palette (both)
2. We can follow a similar approach to what I propose in Save as Markdown behaviour for web #455 a direct export (no dialog) to the project folder structure at /exports/references.bib.

This is a follow-up after #425
