Method name is incorrect in 2019 day 18 write-up.

[SSteve]

After "Here's the updated function:" in the 2019 Day 18 write-up, the method name is still minimum_steps but should be explore.

Thanks so much for doing these write-ups. They are a generous contribution to the AoC community. When I get stuck on an advanced problem I always know I'll learn something by coming here.

Thank you @SSteve I will fix this with the next batch of typo fixes, and thanks for the kind words too :)
