Update ktlint version

[ratnikov]

Hey folks,

I noticed that the bundled ktlint version is quite a bit behind the latest (0.49.1 vs 1.3.0) which causes quite a bit of a linting discrepancy. Do you have a suggestion on how I should approach this? Ideas I have so far:

1. Maybe there's a way to override version in rules_kotlin, though I'm not sure exactly how...
2. Send a PR to bump the version (that's a bit tricky since my company is still figuring out the CLA process. :( )
3. Your suggestion here...

Thanks!

@ratnikov I put up a PR upgrading the internal version #1184

The infrastructure is there to support dynamically setting remote versions via kotlin_repositories, wouldn't be hard to extend that to support KtLint as well. Happy to review a PR for this if you want to take a stab at putting one up!
