Allow app-name configuration to change the name of the PWA

[Lan-Hekary]

Fixes #
if I have multiple instances for code-server running for every user and I want to install the PWA the name currently defaults to "code-server" which overrides the desktop shortcut.
This fix allows multiple instances to be installed with customizable names.

Thank you!

@Lan-Hekary how does one customize the PWA app name using this code change ? is it a command line argument ?

[Lan-Hekary]

Yes, there are two ways to achieve it.
The easiest way is to add it to config.yaml, like this ==> app-name : "Your name"
and then restart code-server.

The other is, like you said, to pass it as command line line argument --app-name "Yourname"
but in order to make this change permanently if you have it running as a service is a little complex.

For example, for a user named ubuntu:
you have to modify the service to add the argument by executing this :
sudo systemctl edit [email protected]
And type :

[Service]
ExecStart=
ExecStart=/usr/bin/code-server --app-name "Yourname"

you have to clear ExecStart before setting it to a new value.

you may want to add environment variables too, like Password or hashed password under [Service]
Environment=HASHED_PASSWORD=blablabla

See this for reference on how to generate it.
