Some small types fixed in readme and makefile

[jdmaguire]

Motivation

I was following the README and found two small issues preventing me from running the code.

Modifications

One was a typo (I think) for the operator-sdk. The README has --controller-true. I think this is a mistake since I see the operation is --controller=true in the operator-sdk docs and cli on my computer.

The second issue I had was when running make run. Main.go would crash setting up the webhook. Reading

function-mesh/main.go

Lines 151 to 153 in 4ed298a

	// enable the webhook service by default
	// Disable function-mesh webhook with `ENABLE_WEBHOOKS=false` when we run locally.
	if os.Getenv("ENABLE_WEBHOOKS") != "false" {

, it seems ENABLE_WEBHOOKS should be set to false when running locally with make run. I've set it to thus. (An alternative 'fix' would be the README saying to run ENABLE_WEBHOOKS=false make run as opposed to make run.)

These may both be non-issues. Feel free to correct any misunderstanding I have.

Thanks!
