Description:

Currently, handling the VSCODE_EXTENSION_IDS environment variable does not allow for spaces in the string. This change strips all spaces from that variable before it is used to install extensions.

The VSCODE_EXTENSION_IDS handling will be more flexible to allow spaces and thus allow VSCODE_EXTENSION_IDS declarations like the following in Docker compose file:

VSCODE_EXTENSION_IDS: vscode-icons-team.vscode-icons | ms-azuretools.vscode-docker | ...

or nicer mult-line strings when one has numerous extensions.

VSCODE_EXTENSION_IDS: >
  | vscode-icons-team.vscode-icons
  | ms-azuretools.vscode-docker
  | ...

Benefits of this PR and context:

This allows the user to include spaces in the VSCODE_EXTENSION_IDS value, which can improve readability in Docker compose files.

How Has This Been Tested?

I replaced the existing /etc/s6-overlay/s6-rc.d/init-mod-code-server-extension-arguments/run file with my updated version.

I ran docker compose up with each of the following VSCODE_EXTENSION_IDS definitions in the compose file. I then looked at the logging to check that the extension IDs were processed as desired.

VSCODE_EXTENSION_IDS: 'vscode-icons-team.vscode-icons|ms-azuretools.vscode-docker|redhat.vscode-yaml|redhat.java'

VSCODE_EXTENSION_IDS: ' |vscode-icons-team.vscode-icons| ms-azuretools.vscode-docker |  redhat.vscode-yaml  |  redhat.java    '

VSCODE_EXTENSION_IDS: >
  |vscode-icons-team.vscode-icons
  | ms-azuretools.vscode-docker 
  |  redhat.vscode-yaml
  |   redhat.java

VSCODE_EXTENSION_IDS: >-
  |vscode-icons-team.vscode-icons
  | ms-azuretools.vscode-docker 
  |  redhat.vscode-yaml
  |   redhat.java

VSCODE_EXTENSION_IDS: >+
  |vscode-icons-team.vscode-icons
  | ms-azuretools.vscode-docker 
  |  redhat.vscode-yaml
  |   redhat.java

VSCODE_EXTENSION_IDS: |
  |vscode-icons-team.vscode-icons
  | ms-azuretools.vscode-docker 
  |  redhat.vscode-yaml
  |   redhat.java

VSCODE_EXTENSION_IDS: |-
  |vscode-icons-team.vscode-icons
  | ms-azuretools.vscode-docker 
  |  redhat.vscode-yaml
  |   redhat.java

VSCODE_EXTENSION_IDS: |+
  |vscode-icons-team.vscode-icons
  | ms-azuretools.vscode-docker 
  |  redhat.vscode-yaml
  |   redhat.java

VSCODE_EXTENSION_IDS: '
  |vscode-icons-team.vscode-icons
  | ms-azuretools.vscode-docker 
  |  redhat.vscode-yaml
  |   redhat.java
  '

VSCODE_EXTENSION_IDS: "
