Allow the Even Better TOML extension for VSCode to run in Restricted workspaces

[LikeLakers2]

Hello! The VSCode extension "Even Better TOML" currently cannot run in workspaces that run in restricted mode. However, because the extension primarily deals with formatting, syntax highlighting, and so on rather than executing code, I feel that allowing the extension to run in restricted mode workspaces should not be too much of an issue.

If the maintainers agree, then enabling the extension to run in restricted mode is possible via the "capabilities" -> "untrustedWorkspaces" key in the extension manifest (see here for more info).

Thanks for your time!
