Some minor issues in getting started code

[jasonkuhrt]

Hey, while following the instructions at https://www.contentlayer.dev/docs/getting-started I ran into a number of small issues.

1. The paths config did not work for me, I'm currently just doing a direct relative import to content layer directory
2. There are various places in the code that when used lead to TS type errors.

Would a PR to address some of point (2) be welcome?

Hey @jasonkuhrt! Apologies for the delay. I'm giving the website much more attention over the next few months.

If you still want to put a PR together to fix the tutorial issues, I can give it a test on my end to make sure the updates work well.

Otherwise, I'll address in the next few weeks.
