Update "Open in code editor" to support workdir and filepath

[adriengivry]

Problem this feature should fix

When opening a file in code editor (e.g. lua script), the file will be opened, and the directory containing the file will be used as the current workdir. This is an issue since the .luarc.json is at the root of the project, and is required for Lua LSP to function properly.

Expected solution

Update custom code editor command to have both:

• {path}: path to the file
• {workdir}: project folder
  The default editor command could look like:

code {workdir} --goto {path}
