`selector` should default to `name`

[schloerke]

Ex:

shiny-bindings/packages/react/src/makeReactInput.ts

Line 8 in 867dfed

* @param selector The selector to use to find the element to bind to. Defaults to looking for

From 4738b86 , selector was added and it defaults to .{name}. Instead, I believe it should be {name} as you are making the component of type name and no class values are being added.

@nstrayer If this seems like a valid bug, I'm happy to make a PR.

... just looking for confirmation.
