vscode: tweak spell-checking configuration

it doesn't seem possible to override the includeRegExpList for specific
languages/file types if there's a global match, so list the common
languages explicitly to limit spell-checking in comments/strings there.
Other filetypes are using the built-in (or user-configured) defaults.
Add a second section for git-commit files as an example of how to extend
the configuration for other file-types.
