Add RuntimeCodeExecutionMode to runtime.executeCode() in the API

[atsyplenkov]

Hi guys,

Could you please consider making positron.runtime.executeCode() in the API behave like the inner positron.runtime.execute(). It would be super helpful for extension developers like me to have the option to pass positron.RuntimeCodeExecutionMode.* and positron.RuntimeErrorBehavior.* to positron.runtime.executeCode().

This change could be really beneficial, especially when a user wants to run some code in the same R environment without displaying the output, just like how it's currently set up in Positron with the styler package:

positron/extensions/positron-r/src/formatting.ts

Lines 82 to 86 in 1570041

	session.execute(
	`styler::style_file('${stylerPath}')`,
	id,
	positron.RuntimeCodeExecutionMode.Silent,
	positron.RuntimeErrorBehavior.Continue);

Thanks for considering this!
