See #169:
"network/language_server/remote_port" only presents in settings file when it has been modified from the default value from later version of godot.
So it always fail to extraction and return nothing,we can fix that by add a default value.
Also: bump gdscript-eglot-version to 4.5
Fixes#121.
* gdscript-eglot.el gdscript-eglot-version: added customizable option for
the godot version in use.
(gdscript-eglot-contact): added function to allow `eglot' to find the godot LSP
port.
* gdscript-mode.el Commmentary: double space after period.
(require 'gdscript-eglot): require this new file.
(with-eval-after-load 'eglot): tell eglot how to find godot LSP.
