chore(prettier): add trailingComma option and set to es5.

By default `trailingComma` option is set to `all` when not defined, and this made changes to extension.ts file by adding unnecessary trailing commas to function and method params. This could be seen in all the `showInformationMessage` method calls.

By defining the option with the value `es5`, trailing commas will only be affective on arrays and objects, not functions and methods.
