extend setting 'headerTemplate' with scope...

[ha5ch]

.. scope: "resource" will able to setup separate .vscode/settings.json per workspace folder

with this small change single options can be set on workspace-folder level.
An example: The following FOLDER structure

project_root
├── sub1
│   └── sub1.md
├── sub2
│   ├── sub2.md
│   └── .vscode
│       └── settings.json
├── root.md
└── .vscode
    └── settings.json

With a simple workspace (only one root), the settings of project_root/.vscode/settings.json will be used for all Markdown files. (if markdown-pdf.headerTemplate isn't set, Userlevel settings or Default settings will be used).
At this point, same behaviour as now.

But when you add project_root/sub2 as separate folder to the workspace:

• the settings of project_root/sub2/.vscode/settings.json will be used for project_root/sub2/sub2.md.
• For project_root/root.md the settings from project_root/.vscode/settings.json will be used.
• For project_root/sub1/sub1.md the Userlevel/default settings will be used, as long as you haven't set separate workspace level settings (inside the .code-workspace file for the loaded workspace)

in that pull request, I only changed headerTemplate because currently this is the only option that I need. but you could also change the/some other options, to made them individual set able on workspace-root level!

This could maybe also a solution for #173

Extended Example

project_root/.vscode/settings.json

{
  "markdown-pdf.headerTemplate": "<div style=\"font-size: 9px; margin-left: 1cm;\">project_root level Header</div>"
}

project_root/.vscode/ws.code-workspace

{
  "folders": [
    {
      "path": "../"
    },
    {
      "path": "../sub1"
    },
    {
      "path": "../sub2"
    }
  ],
  "settings": {
    "markdown-pdf.headerTemplate": "<div style=\"font-size: 9px; margin-left: 1cm;\">workspace level Header</div>"
  }
}

project_root/sub2/.vscode/settings.json

{
  "markdown-pdf.headerTemplate": "<div style=\"font-size: 9px; margin-left: 1cm;\">sub2 individual Header</div>"
}
