Option to override requireConfig if the command is explicitly called

[jasonwilliams]

Is your feature request related to a problem? Please describe.
I navigate many codebases and sometimes hitting save runs prettier automatically which isn't what I've intended. To get around this I've set prettier.requireConfig: true. This will at least only run prettier if the codebase is setup for prettier and helps a lot.

However, sometimes I do want to format something, and running "Format with..." -> "Prettier" does nothing, because the config is set to prettier.requireConfig: true. But in this case I explicitly want to format the document (or selection). It is annoying having to toggle requireConfig back and forth.

Describe the solution you'd like
I would like "format on save" to continue to respect the requireConfig flag, but running the format command should still format (as I've explicitly called that function)

Describe alternatives you've considered
Another alternative could be a separate command for overriding the formatting, but i don't think that will work, as VS Code seems to already have a way of calling prettier's "format" command. I think instead (if we don't want to break backwards compatibility) we would need a setting to allow override if the command is called
