Hardcoded path to Electron

[M-II-R]

A problem:
After Nyxt is compiled, it tries to use Electron supposing that it's located on the same place it was while building. After removing/renaming build folder, Nyxt can't be launched. For example, I have built it in /tmp/nyxt-buildfiles/arch/.

Steps to reproduce the issue

1. Build Nyxt (it's easier using scripts in my repo: https://codeberg.org/M-II-R/nyxt-buildfiles/)
2. Remove or rename build directory.
3. Launch Nyxt.

Information

• OS Name+Version:
  Arch Linux, kernel release 7.0.9.
• Installation method (Flatpak, Guix, package manager, build from source):
  Build from source, then install with Pacman.
• Nyxt output while launching Electron:

Nyxt version 4
