feat(code-server): add machine settings option

[djarbz]

Should resolve #27

The goal is to provide a method for template owners to configure default Machine Settings that can be overridden by developers via User Settings and repositories via Workspace Settings.
This option allows template owners to push new settings options with a template release that would not be ignored because the setting file already exists.
This also formats the settings.json file if jq is installed.

Eventually, I would imagine the current settings option will be depreciated in favor of this option.

I'm going to test this out in a template, and then I will update.

I was taking another look at everything before testing, I noticed something about the settings.json formatting. You are using jq when it's installed, which is great, but maybe we should check if jq is available first and install it automatically if it's missing? That way we can ensure consistent formatting for all users rather than having it depend on whether they happen to have jq installed already.

[djarbz]

I'm hesitant to add a dependency just for that.
Updating the package list and installing takes time, I would rather a quick stand-up than to have to wait for jq to install.
Formatting is moreso a nice-to-have, I don't expect many to manually modify the file and rather edit from the settings menu.

[DevelopmentCats]

Okay that works.

I'll test this when I get home in a bit and then I'll merge.

[DevelopmentCats]

Tested and its working fine.

Need to add Versions in README for code-server

[DevelopmentCats]

@djarbz Can you make a new PR so we can update the versions and then merge?

[djarbz]

@DevelopmentCats Do I need to update the versions? From what I had read in the contributors.md, that was handled internally. Unless I am mistaken?

[DevelopmentCats]

@djarbz

We will need to manually update them for now.

In the near future this will be handled automatically, but as of now we will need to update the readme before release

edit:

I'll also take a look at updating the contributions doc to make it a little more clear.
